Vaisala HMW112 Humidity and Temperature Transmitter

HMW112 Humidity and Temperature Transmitter, Wall Model, IP65, Current Loop, 2% accuracy.
The analog wall mounted Vaisala HMW112 Humidity and Temperature Transmitter is designed for accurate humidity and temperature measurements in HVAC applications where the instrument may be exposed to water splashes. IP65 classified enclosure ensures that the sensor and electronics remain intact.

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

HMW112 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
