The MP400A standard analogue meteo sensor with ROTRONIC fixed sensors is a combined humidity and temperature sensor.

The MP400A is designed primarily for meteorological and general outdoor applications. The sensor’s DC operation and low power consumption make it particularly suitable for remote locations. The probe only needs to be powered for 0.25 seconds during each measurement. The linear output signals are compatible with the requirements of most data acquisition systems.
