METER GROUP ECH2O 5TE SOIL MOISTURE SENSOR
Previously known as Decagon 5TE Soil Moisture Sensor
The 5TE lets you monitor bulk electrical conductivity (EC), in addition to volumetric water content (VWC) and soil temperature. Monitoring salt levels can be as important as monitoring soil moisture in water-limited areas. The 5TE allows you to measure salt levels through bulk electrical conductivity.
