Applications
The profile sampler differs from other sampling devices by taking a rectangular sample from the top layer. The device makes it possible to take a sizeable and virtually undisturbed sample. The roots, up to a diameter of 2 centimetres, are included in the sample. The sample is easy to remove, which reduces the risk of disturbance to a minimum.
The soil coring kit for chemical research, for establishing the presence of volatile components in the soil, is suitable for augering down to a depth of 5 metres. This kit allows sampling for environmental research of soil containing volatile components. The method employed meets the NEN 5743 standard.
With our special coring kit, volatilisation and oxidation of components in soil samples can be prevented as much as possible. This is due to the fact that during sampling, the sample is pushed into the sample tube, after which the tube is shut off. This will optimally prevent volatilisation and oxidation of the soil sample. So the sample under no condition comes in touch with synthetic material. This method meets the NEN 5743 norm (soil or sediment sampling with volatile components). You can also combine it with the methanol method.
The sample has a volume of 226 millilitres. The set therefore also is suitable for the determination of volume percentages of humidity in samples from undisturbed soil. With this set it is possible to take samples to a depth of more than 5 metres.
The samples are taken with a small coring apparatus fitted with thin-walled stainless steel sample tubes. The sampling tubes are preferably pushed into the soil by hand, but a steel hammer with nylon heads can also be used.
After taking the sample, the sample tubes can be locked and cooled for transport to the laboratory. Here sub-samples can be taken from the sample tube, applying a small gauge or apple-corer. The samples can also be removed using an extruder. All the parts, except the caps, can be decontaminated over and over. After decontamination the equipment can be used again. Please note that this set is not suitable for stony soils.

Royal Eijkelkamp has developed a varied range of undisturbed core samplers to meet all needs in the field and in the laboratory.
The percussion drilling set for heterogeneous soils with RD32 and a gasoline powered percussion hammer (Cobra TT) is standard equipped for drilling to a depth up to 5 metres.
The percussion drilling set is perfect for soils with bricks or large stones, which makes it suitable for use in urban areas or industrial sites, for example. With this drilling set you get beautiful clean samples without the use of lubricants.
The set is equipped with extremely robust rods and gouges. The different diameters allow efficient, fast and light work. Please note that this set does not replace cutting with a diamond core and is not intended for fibrous material. Do not use the set on dry glacial loam, porosity is required.
RD32-connection
The percussion drilling sets are equipped with RD32-connection extension rods and percussion gouges are screwed together using a coupling sleeve. The RD32-connection is used in firmer, dryer soils. The RD32-connection takes very little time to attach and take off. The RD32-rods connect together by means of a coupling sleeve, which means that the massive extension rods have the same diameter along the entire length, which makes them very strong.
Applications

For larger depths we offer (Sonic)drilling and CPT equipment.
* Please check that the stones and/or bricks do not exceed the diameter of the percussion gouges too much. If the stones can be pushed aside by the cutting shoe, or they can enter the gouge, there’s no problem. Too large stones, or bricks that can not move, shall block the drilling and most likely break or damage the cutting shoe on the percussion shoe. However, cutting shoes can easily be replaced.

Different samplers for water are included in Royal Eijkelkamp’s assortment. The difference is in the material and the way of sampling. This can be done by sampling the sediment while the water is flowing through the sampler, or by sampling a vertical column from the sediment in (still) water.
The complete Rhizon soil moisture sampler system supplies a range of miniature soil moisture samplers. The Rhizon samplers are used for repeated and reliable sampling of all dissolved components in the soil solution.
This unique sampler is made of porous plastic material (PES) and has standard 0.15-micron pores. The sampler is reinforced with wire and dissolved organic and inorganic matter will not be absorbed on the soil moisture sampler. A horizontal placement in moist soil is preferred. Water acts as a lubricant during inserting. Due to the minimal disturbance the soil will quickly settle, resulting in a good sampler-soil contact. Optional is co-extruded tubing (PE inside / PVC outside) 1 millimetre internal diameter, Luer-connectors and protective caps. This sampler type has a length of 9 centimetres and a diameter of 4.5 millimetres. For installation at greater depths, a standard sampler with PVC extension pipe can be used.
This set is ideal for studies on undisturbed soil columns and pots with plants, the standard Rhizon soil moisture samplers can be inserted through the wall. A sample is obtained by placing the sampler under vacuum, by using a vacuum tube or a syringe. During sampling, the pH value of the soil is not affected. The standard set can be extended with various accessories.
Notes
The Rhizon soil moisture samplers are available in various designs:

The Van Veen grab is used for sampling disturbed sediment. This device is used with a rope/cable and is manually controlled. The Van Veen grab is available in four different capacities.
With the Beeker sampler, you can take undisturbed sediment samples in a fast and certain way from watery sediment to unconsolidated sand to a depth of 5 metres. Even in watery conditions, the sample will not be lost thanks to the closable cutting head. Using additional extension rods, sampling to greater depths is possible in certain cases. The Beeker sediment core sampler works almost the same way as a Multisampler / piston sampler, but with a lockable head with inflated membrane.
Method
The samples are taken in a transparent tube which allows you to make a clear profile description. The sampler has long sampling tubes of 1 metre. The piston can be operated directly with a rod, so that the sample can be pushed out of the sampler on site into a sample bucket. The apparatus is pushed or hammered into the sludge. To avoid compaction of the layers, a piston is held at a stationary position relative to the sludge. The sample can then be emptied into a clean stainless-steel bucket, or layer by layer in wide necked sample jar. It is not necessary to assemble and disassemble the apparatus with every new sample. This set comes in an aluminium transport case.
Extended set
In addition to the standard set (04.23.SA), an extended set (04.23.SB) is also available for sampling and discharging core samples with a length of 1 metre or 1.5 metres, in bucket or jars and to transport and divide in subsamples with water pressure. This set is suitable for sampling of submerged soils to a depth of 5 metres from very aqueous sediments to unconsolidated sand.

Grab samplers are used for taking disturbed samples from the bottom of lakes, rivers, etc. Various designs can be supplied that are cable or rod operated. This instrument is suitable for sampling in soft sediments, free from debris and plant growth.
The Beeker type sediment sampler is rod-operated and has a closable cutting head and piston. This sampler is used for high accuracy sampling of very soft to medium hard sediment layers. A standard and extended set are available.
Easily collect samples at the bottom of lakes, rivers with the Van Veen grab. Simply open the jaws and take a ‘grab’ when reaching the bottom. When hoisting the rope up again the jaws will shut tight and the sample is taken. The Van Veen gab will give you a fast indication of the sediment type and is available in four different sizes. The stainless steel construction ensures that the Van Veen grab is strong and of high quality.
Method
The mode of operation of all Van Veen grabs is the same. At the surface the jaws are pushed open and kept in that position by a hook. To keep the hook in the right position the Van Veen grab should be sunk at a steady, not too high, pace. Both jaws are fitted with holes to allow air to escape during the sinking. If these holes were not there, the air would escape when taking the sample, which would result in interference with the sample. As soon as the jaws touch the bottom, the hook loosens its grip, so that, when hoisting the rope again the jaws will shut tight because of the leverage by the rods.
It is recommended to take at least 6 samples from every location and to base your conclusion on the total of the samples. This is especially important when the bottom is less regularly shaped and the bottom material consists of a mixture of materials.

The water bottom sampler has been specially developed by Royal Eijkelkamp for taking soil samples from water bottoms. Most of the sets are suitable for undisturbed sampling of soils under water.
The bed-load transportmeter, type Arnhem is a sampler, used to measure bed-load of coarse sand and fine gravel in rivers and in other watercourses.
The bed-load transportmeter, type Arnhem is a streamlined sampler mounted in a frame. It consists of a mouth followed by a basket of fine wire meshing (width of the mesh is 300 μm). It is used to obtain samples of sediments and gravel rolling along the river bed.
The sharp decrease of the velocity in the wide sampling chambers causes the sediment material to settle there. The mouth allows water and fine particles to pass through and is shaped to maintain the initial water velocity. A tail fin mounted on the frame keeps the sampler in up-stream direction.
The results of the measurements are influenced by the shape of the bed (ridges, dunes, flat beds, etc.). For a successful measurement knowledge of the relief of the bed is essential. The sampler can be discharged on board using the sample trough.

The determination of the soil moisture tension (in hPa, mbar or cbar) in the soil is an important aspect of complete agricultural physical soil research. Our tensiometer makes it possible to determine the soil matric potential (and thereby the moisture content of the unsaturated soil), by direct measurement in the field.
The Royal Eijkelkamp Watermark soil moisture measuring system is used to read out soil moisture sensors that measure moisture tension in the soil. With this soil moisture measuring system, more accurate measurements are possible due to the more consistent distribution of the pores.
The measuring principle is similar to that of the gypsum block system. The special sensors however do not dissolve in the soil and have a more consistent distribution of pores so that more accurate measurements are possible.
The soil moisture sensors, which have a measuring range of 0-200 kPa (0 – 200 cbar), can be used individually or in combination with a PVC tube (in various lengths) for measuring the moisture tension. The condition for reliable measurements is the optimal contact between sensor and soil. Using the special auger the holes are pre-drilled so that the soil moisture sensors can be placed at various depths. The sensors are buried permanently and have an average life of 3-5 years.
By using a soil temperature meter the temperature measured can be set in the soil moisture meter allowing for temperature correction. The electrical resistance is converted by the soil moisture meter into moisture tension in kPa. The soil moisture sensors can be used as a replacement for tensiometers in most agricultural and landscape irrigation environments. If a series of soil moisture measurements is required the soil moisture sensors can be connected easily to a datalogger.

Measuring the soil moisture suction tension can be done through indirect means with a durable non-salt-sensitive block, equipped with an ‘open’ condenser. The isolation characteristics of this capacitor can be measured. With our equipment it is possible to derive and display the value of the suction.
The inexpensive and easy to install Watermark soil moisture sensor is a granular matrix soil moisture sensor to measure soil moisture tension between soil particles. This is relevant for plant growth and soil stability.
Watermark sensors can be used as an economical and maintenance-free replacement for tensiometers in most agricultural and landscape irrigation environments. These sensors will not dissolve in the soil, are insensitive to salt and frost resistant.
They monitor the current situation in the soil. An alternating current is applied to a sensor that is sensitive to soil moisture tension. Due to the consistent pore distribution of each sensor, a reasonably accurate measurements will be gained, with a measuring range of 0 – 199 kPa (0 – 199 cbar).
The soil temperature measured can be set in the soil moisture meter (14.27.01) allowing for temperature correction. The electrical resistance is converted by the soil moisture meter into moisture tension in kPa.

The mini hand sieve set is used to determine the particle size distribution of small quantities of soil. This mini set is pocket-sized and contains several sieve discs: Ø 100 mm, sieve openings: 2.0, 1.0, 0.500, 0.250, 0.125 and 0.063 mm.
The composition of particles, sizes and types (also called grain size distribution or texture) is one of the most important characteristics of the soil. This influences many properties of the soil such as for instance the ease of tillage, the capillary conductivity of a soil, the available moisture (for plants), the permeability of a soil, compaction, etc.
Furthermore the determination of the particle size is essential for the assessment of the availability of substances for the flora and fauna, the behavior of a substance in the soil and the determination of the quality of the soil

This sand ruler is a disc made of transparent material with selected samples (standard graduations). The sand ruler is an excellent indicative aid in estimating granular composition. It is possible to classify the sand fraction by using the sand median.
An important quality of a soil (in a soil profile) is the grain size distribution or texture. Agricultural soil properties are greatly determined by the texture of a soil: for example the ease of tillage, the capillary conductivity of a soil, the available moisture, the permeability of a soil, compaction, rooting possibility, etc.
A sand ruler is a disc made of transparent material with standard (specimen) samples. It is an excellent indicative help in determining the particle size distribution or to estimate the granular composition.
Method
By using the sand median, it is possible to classify the sand fraction. A representative proportion of the sample to be tested is rubbed dry with the fingers in the palm of the hand. The sample is then placed in the hollow area in the center of the ruler. The average grain size is now judged by comparing the average grain size of the sample with the specimen in the ruler.

Determination of the particle size provides insight into the behaviour of a substance in the soil, and it helps to determine the quality of the soil. Particle size analysis is also important to research if soil provides enough sustenance for both flora and fauna and how easily it can be extracted from the soil. That in turn determines how suitable soil is for a certain use, such as agriculture.
The hydrometer method is an accurate way to determine the particle size distribution in a soil sample. This kit is a complete set to analyse the grain-size of of the smallest fractions in soil samples.
With the hydrometer method, a sample is first cleaned of organic matter. It is then weighed and dried, suspended in water, and sieved.
The solution that passes through the sieve is transferred to a measuring cylinder with water. Hydrometer readings are then taken at regular intervals. These hydrometer readings, combined with sedimentation time, are used to determine the grain sizes according to the Stoke’s Law.
The hydrometer kit contains:
A number of hydrometers
Sedimentation cylinders
Thermometer
Glass container
Heating element with thermostat and stirrer
Soil stirrer
Various accessories
The hydrometer set is used to analyse smaller fractions of soil samples. To perform a complete analysis of the grain-size of soil samples, the granular composition test set is required for the analysis of coarse fractions and a pipette apparatus for fractions smaller than 38 μm.

Determination of the particle size provides insight into the behaviour of a substance in the soil, and it helps to determine the quality of the soil. Particle size analysis is also important to research if soil provides enough sustenance for both flora and fauna and how easily it can be extracted from the soil. That in turn determines how suitable soil is for a certain use, such as agriculture.

Soil air permeability is one of the most important parameters for the aeration in agricultural soils. It has a significant effect on plant growth and crop production. Both air and water are essential for plant growth, and air permeability determines in large part how much oxygen the plant roots have access to.
Complete set for the pF determination of soil samples. Measures the full soil retention curve, pF 0 – 4.2 (0 – 15 bar). Includes the sandbox, the sand/kaolin box and membrane apparatus, with a soil sample ring kit for taking undisturbed samples.
With the hydrometer method, a sample is first cleaned of organic matter. It is then weighed and dried, suspended in water, and sieved.
The solution that passes through the sieve is transferred to a measuring cylinder with water. Hydrometer readings are then taken at regular intervals. These hydrometer readings, combined with sedimentation time, are used to determine the grain sizes according to the Stoke’s Law.
The hydrometer kit contains:
A number of hydrometers
Sedimentation cylinders
Thermometer
Glass container
Heating element with thermostat and stirrer
Soil stirrer
Various accessories
The hydrometer set is used to analyse smaller fractions of soil samples. To perform a complete analysis of the grain-size of soil samples, the granular composition test set is required for the analysis of coarse fractions and a pipette apparatus for fractions smaller than 38 μm.

The PF curve shows the relationship between the soil’s moisture contents and suction. These moisture contents vary with the same suction and differ per type of soil. With the right equipment, the pF curve can be determined for each type of soil, which clearly shows the availability of water for that type of soil. We offer three laboratory devices to make a complete pF determination.

Soil structure is largely determined by the formation and presence of soil aggregates. These aggregates can disintegrate due to mechanical and physico-chemical forces and lead to pore clogging and infiltration reduction, resulting in water erosion and/or spraying. The ‘wet sieving method’ is the method to investigate aggregate stability against water erosion.
Air pycnometer according to Langer, complete set including a calibration block. The apparatus is suited for sample rings with a maximum diameter of 53 or 60 mm (max. height 51 resp. 40 mm) and has a measuring range of 0-115 cm3.
The vacuum air pycnometer has been designed to determine the volume and density of solid material, such as soil samples. It can be applied in every field where it’s important to calculate a specific weight, such as soil research, powder- and granulate investigations for the pharmaceutic industry, road building, brick factories, and the food industry (coffee, leguminous plants, etc.). The apparatus is especially useful to measure the volumes of irregularly shaped objects.
The principle
An under pressure is created in the vacuum bell that the object to be measured is placed in. Depending on the gas volume present in the bell, more or less air will be extracted. The quantity of the air present is independent of the volume taken by the object to be measured. After the under pressure has stabilised, the volume of the object can be read from the calibrated scale.
Remarks
Applications
The pycnometer can be applied wherever knowing a specific weight is desired:
Limitation: Temperature variations influence the measurements (can be prevented by climate control in the laboratory).

Determination of water permeability, or hydraulic conductivity, is important for agricultural as well as for environmental soil research. The permeability factor, or K-factor, serves as an indication to base the designs of irrigation- and drainage systems on. It’s also of great importance with respect to the extent of the spreading of possible pollution.
The compression and shear test apparatus measures both the compression and shear resistance of an undisturbed soil sample.

Compression and shear stress tests measure a soil’s resistance to deformation when it’s submitted to shear or compression. Altered soil functions, especially the reduced hydraulic conductivities and impeded aeration, could decrease crop growth and productivity as well as the filtering and buffering capacity of soils. Testing shear and compression strength offers valuable insight for soil use.
The calcimeter measures the amount of calcium carbonate, or lime contents, in the soil. This is an important indication of the quality of the soil.

The Scuba BGA is a floating, solar-powered sensor buoy designed to provide early warning of harmful algal blooms, turbidity and other water contaminants.
The Scuba BGA (for Blue-Green Algae) is designed to monitor water quality, specifically algae, temperature, and turbidity. Real-time insights in these parameters will help to take action in time and prevent larger algae problems. Custom alerts will notify you when levels have gotten too high.
Sensor technology
By continuously monitoring the water, the Scuba BGA eliminates the need for manual water sampling and spot checking. This device uses the fluorescence of the pigments in algae and cyanobacteria (blue-green algae) with this it detects the abundance of organism. Chlorophyll-a, present in all algae and cyanobacteria, is the most commonly used indicator of algal growth. Phycocyanin, typically present in freshwater cyanobacteria, is used as an indicator of blue-green algae. The Scuba BGA uses an excitation wavelength of 420 nm for chlorophyll-a and 575 nm for phycocyanin. The measured peak emission wavelengths are 670 nm and 642 nm, respectively.
Power and data transfer
Thanks to the integrated solar panel, the Scuba BGA is self-powered and can continue to operate for up to a year as long as the water does not freeze. Fully charged, it can function for 2-3 weeks without sunlight. The data collected by the Scuba BGA is sent to a web portal via 4G cellular tehnology. This system automatically switches between three carrier waves to optimise reception. It’s truly an all-in-one system complete with sensors, power supply, data monitoring trackers, and a powerful dashboard. The dashboard also tracks the GPS coordinates of your devices so you’ll always know where it is.
The buoy is suitable for both fresh and salt water and equipped with a built-in sensor wiper, to keep the sensor clean and functional.
Installation of the buoy is easy; simply place it in a waterway, connect it to an anchor (available separately) and it will automatically start collecting data.
The instrument measures the following parameters:
The following options are available for the Scuba BGA
