ECH2O Check
The hand-held ECH2O Check gives you a quick readout of your installed EC-5, 10HS, EC-10 and EC-20 sensors. Plug an ECH2O sensor into the ECH2O Check, press the left button, and get an instant reading of water content. You can adjust the calibration of the ECH2O Check for the soil sensor you are measuring. Readings are displayed in units of volumetric water content (m3/m3), inches per foot (in/ft), or millivolt output.
