Vaisala INTERCAP® Humidity and Temperature Transmitter Series HMS80 are designed for outdoor measurements in various building automation applications. These ±3% transmitters include an integrated radiation shield to reduce the influence of solar radiation on temperature and humidity measurements. 

HMS80 series transmitters can be mounted directly onto a wall or pole without any extra accessories. For fast and convenient configuration, the most popular control parameters in free cooling control – dew point temperature, wet bulb temperature, and enthalpy – are selectable using dip switches.
