Controller allarme gas GDB12/GDB15

Descrizione

GDB12 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 reaches or exceeds the preset alarm value, the controller immediately sends out an audible and visual alarm to remind us to take safety measures in time, and start 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 a modular point-to-point structure design, which is simple to operate on site and easy to replace, making it easy for users to use and maintain.
