HMP110 measures air temperature and relative humidity, which the weather station uses for calculating the dew point. Humidity measurement on the sensor is based on the capacitive thin film polymer HUMICAP® sensor. Temperature measurement is based on resistive platinum (Pt100) sensors.
HMP110 is installed inside radiation shield DTR504, which ensures proper ventilation while protecting the sensor from solar radiation and precipitation. Using the DTR504, HMP110 is installed on the support arm.
