Auger Kits for Pore Water Samplers and Tensiometer
The cutting edge of the auger has a tapered tip similar to the shape of a Tensiometer or pore water sampler. Thus, the bore hole is large enough to insert the shaft, but the cup will have a tight and perfect fit to the soil.
The not recommendable slurrying of the cup with quartz clay can be avoided.
A divisible auger set includes:
- Cutting edge with tapered tip
- Handle with hammering head
Benefits
- Simplifies installation of shafts
- Avoids slurrying
- Multipart - divisible - extendable

SK20 Suction Cup for Pore Water Sampling
The SK20 uses ceramic cups made from Al203 sintered material which allows for sampling and analysis for nitrate and common organic and inorganic substances. Applications Continuous/discontinuous extraction Nitrate, chloride, sulphate, calcium, sodium, ammonium, phosphate Benefits Very low dead… » Learn more
SPE20 Suction Cup for Pore Water Sampling
The SPE20 contains a specialized membrane specifically designed for tough applications such as sampling heavy metals and where porous ceramics are inappropriate. Applications For detection of herbicide, pesticide, and heavy metals Benefits Only materials with sample contact are nylon and… » Learn more
SIC20 Suction Cup for Pore Water Sampling
The SIC uses a specially designed Silicon Carbide (SiC) cup instead of the ceramic cup. SiC is sintered at 2500 °C and is chemically much more passive than ceramic or borosilicate. The bubble point is 90 kPa. Applications Continuous/discontinuous extraction Benefits High permeability Low… » Learn more
SKS20/SPES20/SICS20 Suction Cups With Shaft Storage For Pore Water Sampling
The SKS20/SPES20/SICS20 allows for water and solute collection from depths down to 8 meters that could not normally be collected from other pore water samplers. Available with all three sampling cup materials (Al203 Ceramic, Polyethylene Membrane, and Silicon Carbide). Applications Thanks to… » Learn more
