Zhengzhou Winsen Electronics Technology Co.,Ltd concentration may have reached explosive and severely dangerous concentrations. 7. Avoid exposing combustible gas sensors to lead compounds, silicone resins, and chlorinated hydrocarbons. Although some organic vapors (such as leaded gasoline, halogenated hydrocarbons) may poison the sensor and temporarily stop its normal operation, resulting in a decrease in sensitivity, in most cases, calibration can restore its function. 8. Long-term exposure of the module to a certain concentration of combustible gas or toxic and harmful air may increase the...
