Soil Sampling Equipment

Soil sampling is performed for a number of reasons. These include determination of soil contamination, identifying the horizontal and vertical extent of contamination and investigating the relationship between soil and ground water contamination. Soil can be sampled at the surface or below surface depending on the type of information required. Soil is typically divided by depth into two categories: surface and subsurface. Surface soils include the zone between ground level and 24 inches. Subsurface soils include any depth below 24 inches (please note that for radiological sampling, surface soils are considered to be in the top 6 inches, or 15 centimeters only). There are several different types of samplers that can be used to collect a soil sample at any depth.

Soil sampling kits are designed to provide all the items needed for sampling in convenient carrying cases. Used by soil scientists, agronomists, and construction companies for site investigations. Available in different auger sizes and connections.

Soil Moisture Measurements Stevens GroPoint Probe

Stevens GroPoint Soil Moisture Probes

Stevens GroPoint Probes simplify volumetric soil moisture content measurements across multiple depths using a single probe. Designed for vertical installations, the probe is available with multiple sensor segments (each 15 cm long). GroPoint provides true soil profiling quantification, measuring the average moisture content across the entire length of each segment. This unique technology allows monitoring of water movement through the soil continuously, rather than at discrete sensor depths. These sensors are designed to install quickly with minimal soil disruption using an insertion pilot rod and slide hammer tool.

  • Lightweight and sleek design
  • Low power operation – suitable for dedicated applications
  • One SDI-12 address used to read all segments (optional RS-485)
  • Patented TDT technology for scientific-grade accuracy and stability
  • User-calibrated moisture readings using 3rd-order polynomials
  • Fully potted electronics for excellent durability
  • Configure with or without temperature – temp sensors placed
    every 1 or 2 segments
