Get more out of every field and lab session with our time-saving—and compliant—hydraulic conductivity solutions. The SATURO infiltrometer even combines automation and simplified data analysis together in one system. 

SATURO

We think you should spend less time on complex processes and more time being productive. That’s why we automated almost everything in the new SATURO infiltrometer.
  • Measures field saturated hydraulic conductivity
  • Fully automated and portable infiltrometer
  • Capable of unattended measurement

KSAT

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

HYPROP 2

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.
explore HYPROP 2

TEMPOS

More accurate than any thermal properties analyzer in its class, with an incredible one-minute read time.
  • Accurate thermal properties analyzer
  • New one-minute read times
  • ASTM 5334- and IEEE 442-compliant
explore TEMPOS

VARIOS

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

TEROS 21

The TEROS 21 matric potential sensor is incredibly easy to use and surprisingly affordable.
  • Full-range soil water potential sensor
  • Accurate. Easy to use. No recalibration.
  • Onboard temperature measurement
explore TEROS 21

TEROS 12

The all-new TEROS 12 soil moisture sensor delivers an excellent price-to-performance ratio in a device that is easy to use and includes electrical conductivity.
  • Long-life soil moisture, temperature, and EC sensor
  • Increased volume of influence (1010 mL)
  • Robust, epoxy body for tough field conditions
explore TEROS 12

TEROS 54

We designed the TEROS 54 soil moisture profile probe to make every step of your measurement process easier—without sacrificing accuracy or durability.
  • Multi-depth profile probe measures water content and temperature
  • Easy plug-and-play operation
  • See all your data remotely in real-time
explore TEROS 54

ATMOS 41

The world's best all-in-one weather station for atmospheric measurements that doesn't limit you with other sensors.
  • Measures 12 weather variables
  • Designed for continuous deployment in harsh climates
  • Connect to ZL6 for data capture and management
explore ATMOS 41

Get even more time back when you use our instruments together.The HYPROP and the KSAT use the same soil core, so you can take saturated and unsaturated hydraulic conductivity measurements and generate a soil moisture characteristic curve, simplifying both processes.

“​​The SATURO allowed us to do many tests in a short amount of time to establish a threshold of where good infiltrating soils and poor infiltrating soils were located. This enabled us to change the design on the fly.  The double ring infiltrometer takes significantly more time to do a test, and time is of the essence when the contractor wants to backfill the area and get things moving. It was nice to have a tool that got us the information we needed more rapidly.”

We believe in education

We're scientists. The quest for knowledge is in our blood. We've spent decades learning the best way to measure pretty much everything, so you can access a wealth of information.
