Product description

The GDB3 gas alarm controller is a multi-point monitoring gas alarm developed by our company. It is used to detect the concentration of the gas to be tested in the ambient air. When the concentration of the gas to be tested in the environment is detected to reach or exceed the preset alarm value, control The device immediately sends out an audible and visual alarm to remind us to take safety measures in time, and activate the execution equipment to control the drive exhaust or other external control equipment to prevent poisoning accidents, explosions, and fires, thereby ensuring the safety of life and property. The controller adopts modular point-to-point structure design, simple on-site operation and convenient replacement, which is convenient for users to use and maintain.
