With the indicator signal output;
Dual signal output (analog output, and TTL level output);
Low TTL output valid signal(output low signal light, which can be accessed microcontroller IO port).
Analog output increases with the concentration, the higher the concentration the higher the voltage;
The ozone gas with high sensitivity (detection concentration range 10PPB-2PPM)
Long service life and reliable stability;
Rapidly response and recovery characteristics;
