Carbon dioxide CO2 Gas Alarm Controller 2 channels to 64 channels

                                GDB9 gas alarm controller

GDB9 gas alarm controller is a multi-point monitoring gas alarm developed by our company for detecting the concentration of the gas to be measured in the environment. When the concentration of the gas to be measured in the environment reaches or exceeds the preset alarm value, the controller immediately sends out Sound and light alarm, and drive exhaust or other external control equipment to prevent poisoning accidents, explosions, and fires, thereby ensuring the safety of life and property.
