HMS112 Humidity and Temperature Transmitter for Outdoor Measurements in HVAC Applications

The analog Vaisala HMS112 Humidity and Temperature Transmitter is designed for accurate humidity and temperature measurements outdoors. HMS112 includes an integrated radiation shield to protect the sensor from solar radiation and rain.

With RH accuracy of ±2 %RH, the transmitters have been calibrated with 3-point NIST traceable calibration (certificate included).

HMD112 transmitter is equipped with the proven HUMICAP® 180R sensor. The sensor’s superior long-term stability minimizes maintenance needs throughout the transmitter’s lifetime. If necessary, the transmitter can be field-calibrated using either an HM70 Hand-Held Humidity and Temperature Meter, or a PC connection.

Analog outputs are preset at the factory to:
Channel 1: 4 ... 20 mA = 0 ... 100% RH
Channel 2: 4 ... 20 mA = -40 ... +60 °C (-40 ... +140 °F) T
