Product features:

* indication of signal output indicator;

* dual signal output (analog output and TTL level output);

*TTL output effective signal is low; (output low power signal light, can be connected to the microcontroller IO port)

* the analog output increases with the increase of concentration, and the higher the concentration, the higher the voltage;

* it has high sensitivity and selectivity to ammonia gas;

* with long service life and reliable stability;

* fast response recovery characteristics;

* with mounting holes, easy to fix and install;

The probe can be inserted and designed to facilitate testing.
