Vaisala HMD112D HMD110 Series RH + T Duct Transmitter with Display +/-2 %RH 4...20 mA

The duct-mounted high-accuracy transmitter HMD110 is designed to measure humidity and temperature in HVAC systems. Calculated humidity parameters - like dew point, wet-bulb temperature, and enthalpy - are also available as direct output from the HMD110 transmitter. The IP65-rated transmitter is equipped with the robust HUMICAP® 180R sensor that has superior stability and long-lasting accuracy.

HMD112 Duct-Mount HUMICAP® Humidity and Temperature Transmitter is designed for demanding HVAC applications such as clean rooms and wash-down areas. The IP65 rated housing combined with trusted HUMICAP®180R sensor ensure accuracy, long-term stability and minimize maintenance over the product lifetime.

Features:

• Relative Humidity Measurement 0 ... 100%
• Temperature Measurement -40 ... +60 °C (-40 ... +140 °F) 
• Loop-powered, 4...20mA analog outputs
• 24V input voltage
• 3-point traceable calibration certificate

Highly accurate, proven Vaisala HUMICAP performance

The highly accurate HMD112D transmitters are designed for measuring humidity and temperature in various HVAC applications. The high accuracy and reliability of the measurement enable precise and reliable controls of HVAC systems. The transmitters are equipped with the trusted HUMICAP 180R humidity sensor, which is the robust sensor designed for industrial applications. The sensor's superior long-term stability allows for unbeatable long-term accuracy of the instrument and minimizes maintenance needs throughout the transmitter's lifetime.

Excellent choice for challenging conditions

The IP65-rated HMD112D transmitters are optimal for even challenging conditions, such as cleanrooms, data centers and other industrial settings. The transmitters can also be ordered with the catalytic HUMICAP 180V humidity sensor. The catalytic sensor improves stability especially in hydrogen peroxide sterilized environments where repeated condensation can be expected.

Traceable accuracy

The instruments are individually adjusted and delivered with a traceable (ISO 9001) calibration certificate. If required later on, the transmitter can be easily field-calibrated using Vaisala Handheld Humidity and Temperature Meter HM70 or Vaisala Insight PC software.
