EC-TM Sensor

The ECH₂O-TM sensor incorporates a temperature reading into our traditional soil moisture sensor. Therefore, more data logger ports may be used for additional environmental measurements. Volumetric water content is obtained by measuring the dielectric constant of the media through the utilization of capacitance/frequency domain technology while temperature is measured using an onboard thermistor. The EC-TM sensor incorporates the same high frequency oscillation as the EC-5, which allows the sensor to accurately measure soil moisture in any soil or soilless media with minimal salinity and textural effects. Applications include plant sprouting and growth studies, plant mortality prevention, and greenhouse monitoring.

The EC-TM is the sensor for those who want more than volumetric water content, but do not need the extensive capabilities of the ECH₂O-TE. In the field, the robust design of the EC-TM allows the sensor to be pushed directly into undisturbed soil. However, the compact design of the EC-TM makes it possible to measure volumetric water content in labs and greenhouses. Factory calibrations are included for mineral soils, potting soils, rockwool, and perlite.
