RHT Relative Humidity and Temperature Sensor

The RH/Temperature sensor measures relative humidity (RH) and temperature, making it ideal for use with ECH₂O probes in studying microclimate and evapotranspiration.

It connects to any channel in the Decagon’s EM50 datalogger for long-term temperature monitoring.

The standard cable is 3m with stereo-style plug, but custom lengths and ends are available upon request.

Accessories
The Radiation Shield is HIGHLY RECOMMENDED to protect the Temperature Sensor and the RH/Temp Sensor from ambient interference. Without proper protection, these sensitive devices can give inaccurate readings.
