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.

Proven Vaisala HUMICAP® Performance
The cost-efficient HMDW110 series transmitters are equipped with trusted HUMICAP® 180R sensors.
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.
HMDW110 series instruments are individually adjusted and delivered with a calibration certificate.
The factory calibration is traceable to NIST.
Unrivaled Outdoor Humidity Measurements
The integrated radiation shield of the outdoor models HMS110 and HMS112 enables unrivaled measurement performance.
It reduces the impact of sunshine on temperature and humidity measurements, and ensures measurement accuracy in outdoor conditions.
The most popular control parameters in free cooling – dew point temperature, wet bulb temperature, and enthalpy – are available as output parameters.

Well-Suited for Cleanroom Monitoring
The HMD110 and HMW110 transmitters can be ordered with a catalytic HUMICAP® sensor HUMICAP® 180VHP.
The catalytic sensor improves stability especially in hydrogen peroxide sterilized environments where repeated condensation is expected.
An optional panel display can be added for remote monitoring.
Transmitters can be installed into difficult-to-reach locations, while measurement data can be read from a more convenient spot.
