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
