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.
