Nowadays, with the continuous development of the industrial field, the toxic and harmful substances in industrial production also increase, and the gas detector has become a part of industrial production. It can detect the concentration of toxic and harmful substances in production work and give an alarm when it reaches the preset alarm value to ensure the personal safety of front-line workers. So how does the gas detector perform ventilation calibration?

The baseline reading of carbon monoxide, hydrogen sulfide and combustible materials is zero, and the baseline reading of oxygen is 20.9%.

100 ppm CO

25 ppm H2S

2.5Vol% CH4 (50% LEL)

18.0Vol% O2

The gas flow regulator can provide 0.5 LPM.
