Description
S311 is a pump type single gas detector with high sensitivity.The detection principle of semiconductor or poisonous gas is adopted, which is more suitable to find and detect the location of leakage gas.Compact size, simple operation, easy to carry, can also be accompanied by flexible probe and sampling handle, the hand feels very comfortable.
Detection gas: methane, natural gas, ammonia gas, hydrogen gas, propane, acetone, gasoline, coolant, ethanol, oxide, hydrogen sulfide, paint, thinner, industrial solvent, alcohol, gas fuel and other toxic and harmful gases.
Please choose the gas you want to detect from the below gas list;
