ECHO EA10 Soil Moisture Probe 4-20mA Output
The EA-10 is a standard ECH2O sensor similar in size and specification to the EC-10. The EA-10 is designed for use with industrial data acquisition and control systems. It has a standard 2-wire, 4-20 mA analog interface. Like the classic EC-10 and EC-20 sensors, the EA-10 sensors are for use in medium-textured soil types with low EC conditions. Their typical accuracy in these soil types is ±4% without calibration and 1-2% with soil-specific calibration.
EA-10 Sensor Applications:
* Irrigation control of turf and home landscapes
* 2-wire moisture monitoring
