Four characteristics with the signal output indicator; dual signal output (analog output, and TTL level output); TTL output valid signal is low; (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) with a long service life and reliable stability; rapid response and recovery characteristics; with mounting holes to facilitate fixed installation;
