5TM Soil Moisture and Temperature Sensor
The 5TM sensor incorporates a temperature reading into our traditional soil moisture sensor allowing you to have two measurements in one sensor. 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. 5TM 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 seed germination and growth studies, soil respiration, and greenhouse monitoring.
More of the data that you need
The 5TM allows you to have more than just volumetric water content without the extensive capabilities of the 5TE. In the field, the robust design of the 5TM allows the sensor to be pushed directly into undisturbed soil. However, the compact design of the 5TM makes it possible to measure volumetric water content in labs and greenhouses. Factory calibrations are included for mineral soils, potting soils, rockwool, and perlite.
Integrate with CSI Data Loggers
The 5TM serial or SDI-12 communication means lots of options for integration with systems run by other data loggers (like CSI). Please see our integrator's guide for detailed instructions for using the 5TM in SDI-12 mode.
