ECH2O EA-10 Soil Moisture probe with 4-20mA output
The EA-10 is a standard ECH2O sensor similar in size and specification to the EC-10. It has a standard 2-wire, 4-20 mA analogue interface for use with industrial data acquisition and control systems. The EA-10 has a very low power requirement and high resolution. This gives the ability to make many measurements over a long period of time (i.e. a growing season), with minimal battery usage. Like the EC-10 and EC-20 sensors, the EA-10 sensors are only 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
