  • EE03 humidity and temperature sensor

    Originally designed for the automotive industry, EE03 can be used as stand alone device or as plug in module for data loggers, handheld and other devices. Due to its construction EE03 is ideal for monitoring surface humidity and temperature and especially for detecting near-condensation (dew point) conditions.

    The E+E proprietary sensor coating allows for EE03 to be employed even in aggressive and corrosive environment. Customised versions are possible.
