The E+E EE260 probe is optimized for accurate and reliable relative humidity (RH) and temperature (T) measurement in meteorology and demanding outdoor applications. The design of the EE260 integrates a heated humidity sensing head and an additional T sensing element into one single compact probe. The device is thus compatible with rotation symmetric radiation shields. The dual heating system prevents condensation on the RH sensing element, on the probe head and on the filter cap, which leads to very short response time and fast recovery after condensation. Furthermore, it enables precise RH measurement even under continuously high humidity and condensing conditions.

Besides the measurement of RH and T, the EE260 calculates other humidity related quantities like dew point temperature (Td), absolute humidity (dv) and mixing ratio (r).
