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.

HMS112 Outdoor Humidity, Dew point, Wet bulb, Enthalpy and Temperature transmitter for HVAC, Current Loop or Modbus, 2% accuracy

The analog Vaisala HMS112 Humidity and Temperature Transmitter is designed for accurate humidity and temperature measurements outdoors. HMS112 includes an integrated radiation shield to minimize measurement errors from solar radiation. The transmitter is ideal for controlling cooling towers and for differential enthalpy control of economizers.

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

HMS112 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.
