    Features:

    • With level signal output and alarm signal indicator

    • With analog signal output, voltage range: 0-5V

    • Effective low level output signal can be used to drive PNP transistors. And it can be connected to the OP port of micro-controller

    • The analog output voltage increases with the increase of the concentration. The higher the concentration, the higher the voltage

    • High sensitivity to ammonia, trimethylamine and ethanolamine gases

    • Long service life and reliable stability

    • Fast to response and recover after preheating

    • With mounting holes, it is convenient for fix and install

    • Plug-to-play probe for easy testing

    • With temperature compensation function, it works perfectly
