Ozone and nitrogen dioxide can be detected. If both gases exist in the environment, to determine the amount of O3, it is recommended to add NO2-B43F for calibration and compensation. If there is only one of the two gases, the gas concentration can be directly quantified.

Response time: <80s
Size: 32.3*16.5
Ozone detection range: 20ppm
Overload: 50ppm
Sensitivity: -225 to -750 nA/ppm
