    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
