SRC-H1T1 - Indoor


Active humidity / temperature transmitter for indoor mounting

The SRC-H1T1 measures relative humidity  with a unique capacitive sensor element while temperature is measured by a band-gap sensor. The applied measuring technology guarantees excellent reliability and long term stability.
