Laboratory instruments


A revolutionary new method for soil particle analysis. Automated, simple, and fast—with much less human error than traditional methods.
  • Automated Soil Particle Size Analysis
  • Lower measurement duration of 2.5h
  • Estimated error: an incredible +/- 0.5%


VARIOS automatically generates complete, high-resolution dry down curves with less effort and less cost, so you can focus on what you love.
  • Automated measurement saves time and effort
  • Two measurement methods: continuous and point by point
  • Automatic temperature drift correction


The WP4C measures water potential by determining the relative humidity of the air above a sample in a sealed chamber (conforms to ASTM D6836).
  • Soil water potential lab instrument with fast equilibration
  • Durable and easy to clean
  • Easy to calibrate with saturated salt solutions


The KSAT is the only easy-to-use automated setup for taking saturated hydraulic conductivity measurements in the lab. Best of all, it’s completely integrated.
  • Simplified saturated hydraulic conductivity in the lab
  • Everything completely integrated. Removes human error.
  • Easy to use & ASTM D2434 compliant


Automated calculation of high-resolution soil moisture release curves and unsaturated hydraulic conductivity—in just days, instead of months.
  • Soil moisture release curves in days, not months
  • Curves with hundreds of points
  • Precise and robust. Easy to handle and flexible.


For understanding complex soil issues like clay behavior, specific surface area, and more the VAPOR SORPTION ANALYZER is your simplest, most accurate option.
  • Fast soil-water characteristic curves with hundreds of points
  • Works in the dry soil range (-10 to -475 MPa)
  • Set up a test in five minutes
