HMS110 Series Humidity and Temperature Transmitters

Humidity and Temperature Transmitter Series HMS110

±2%RH outdoor sensors for HVAC?

Vaisala HUMICAP? Humidity and Temperature Transmitter Series HMS110 are ideal for cooling tower control and differential enthalpy control of economizers.?The HMS110 directly outputs wet-bulb temperature, enthalpy and dew-point in addition to RH and temperature. These ±2% transmitters include an integrated radiation shield to reduce the influence of solar radiation on temperature and humidity measurements and to ensure measurement accuracy in outdoor conditions.

HMS110 transmitters are equipped with the trusted HUMICAP? 180R – a robust, general-purpose humidity sensor that functions well in high humidity. The sensor’s superior stability ensures long-lasting accuracy and minimal maintenance throughout the transmitter’s lifetime. If necessary, the transmitters can be field-calibrated using either the Vaisala?HM70 Handheld Humidity and Temperature Meter, or a PC connection.

Two product models are available: HMS110 and HMS112. For details, see the datasheet.
