3306/3308 Combustible Gas Leak Detector detects the presence of combustible gas and measures concentrations

between 0~10000 parts per million (PPM). The Detector indicates the presence of combustible gas by a reading

function much like clicking of a Geiger counter: Above 3200 PPM, the beeper sounds continuously with the

concentration of gas. From 0 PPM to 3200 PPM, the beeper will sound rapidly due to the increasing concentrations

of combustible gas. It provides quick, precise gas leak locating, would be the best instrument for explosion

preventing and safe production.
