The GD-00A2 gas signal is used to continuously monitor the presence of explosive gases in the ambient air and to determine and warn of the maximum safe concentration of such gases. The cylinder is installed in closed compartments where there is a possibility of gas leakage from the device or equipment connected to it. They do not require any additional equipment, power lines or batteries to function properly. The size of a forest, in one body. One power socket ~ 230V / 50Hz is enough for installation. They use a high-tech semiconductor sensor and electronic control system to achieve a high level of detection at a relatively low cost. An optical and acoustic alarm is activated when the set gas concentration is exceeded
