Simple Gas Detection System

TH-1000B Simple Gas Detection System is mainly used in gas analysis industry. The main principle is to sample the measured gas on site for dehumidification and dust filtration, and keep the temperature and humidity of the measured gas constant within a certain range, so that the gas analyzer can detect the concentration normally. The whole process is automated and does not require human intervention. TH1000 gas pretreatment system is used in occasions where the measured gas has little dust, little water vapor, and normal temperature.
