Important information:

Please note that the EE33-M has been discontinued. Do not use/ specify EE33-M for new projects, it is replaced by HTS801 humidity and temperature sensor.


EE33-M is optimised for reliable humidity and temperature measurement in high-end meteorology applications.

  • EE33-M humidity and temperature transmitter

  • HMC01 monolithic humidity sensor

  • EE33-M with radiation shield LAM630

  • Radiation shield LAM630 with control device STEG6003

    A dual heating system prevents condensation on the humidity sensor, on the sensing probe and on the filter cap. This leads to an extremly short response times and fast recovery after condesing conditions.

    The measuring principle with separate humidity and temperature probes enables precise and continuous measurement even at permanent high humidity.

    The proprietary coating protects the sensors and their leads against corrosive and electrically conductive pollution.

    Typical applications

    • Meteorology
    • Wind turbine generators
    • Road icing warning
    • Off-shore measurements
