Humidity and Temperature Transmitters for High-Accuracy Measurements in HVAC Applications

​Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMDW110 measure relative humidity and temperature in multiple HVAC applications. The series includes transmitters for duct mounting, IP65-classified wall transmitters, and outdoor transmitters with integrated radiation shields.

Vaisala HMDW110 series transmitters are equipped with trusted HUMICAP® 180R sensors. They are individually adjusted and delivered with a calibration certificate. The factory calibration is traceable to NIST. Transmitters can be field-calibrated using either an HM70 Hand-Held Humidity and Temperature Meter, or a PC connection.

HMDW110 family includes the following products:
IP65-classified wall-mount humidity and temperature transmitters HMW110/112 for humid areas
Duct-mount humidity and temperature transmitters HMD110/112
Outdoor humidity and temperature transmitters HMS110/112
