GDB15 gas alarm controller

The GDB15 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 reaches or exceeds the preset alarm value, the controller immediately emits an audible and visual alarm to remind us to take safety measures in a timely manner, and starts the execution equipment to control the driving exhaust or other external control equipment to prevent poisoning accidents, explosions, and fires, thereby ensuring the safety of life and property. The controller adopts a modular point-to-point structure design, which is easy to operate and replace on site, and convenient for users to use and maintain.
