HMD/W60/70 Humidity and Temperature Transmitters for HVAC Applications

The duct-mounted HMD60 and HMD70 humidity and temperature transmitters are designed for use in air conditioning applications where accurate and stable measurement of humidity and temperature is required. The transmitters are easy to calibrate on-site without disturbing the measurement.
