Measuring soil moisture either as Volumetric Water Content, VWC, or Soil Water Potential, SWP, is in our DNA. We help researchers, labs and growers around the world by making some of the most accurate and trusted stationary and portable soil moisture sensors on the planet.

The HydraProbe is one of the most peer-reviewed soil moisture sensors, trusted by the USDA, NOAA and a variety of organizations for their weather and soil moisture monitoring networks.

The HandiTrase TDR portable probe is an offshoot of Dr. G.C. Topp’s famous equation and is now used by some of the largest commercial food production companies in the world.
