  • NIST traceable certificate

The Vaisala HMD60 Series humidity and temperature transmitters are capable of measuring temperature (TMD62) or temperature and humidity (HMD62). Temperature measurement ranges from -40 to 176°F (-40 to 80°C) with an accuracy up to ±0.18°F (±0.1°C), while the Vaisala HUMICAP R2 humidity sensor offers up to ±1.5% RH accuracy. All common humidity parameters can be measured including RH, dew point, enthalpy and wet bulb temperature.

The duct mount HMD60 transmitters are housed in an all-metal, IP66-rated enclosure, which is resistant to chemicals and dust, making these Vaisala transmitters ideal for many industrial humidity monitoring applications. Another useful feature of these duct mount transmitters is the ability to remove the electronics without removing the unit from the duct. This allows for easy adjustment and output configuration in the field by the user.
