The combustible gas alarm controller QD6000Ⅱ is a multi-point monitoring gas alarm controller developed by our company, which is used to detect the concentration of the gas to be tested in the ambient air. It can be equipped with multiple detectors for detecting different gas components and simultaneously carry out centralized monitoring of multiple points. This product also has three branch line interfaces and two bus interfaces, which can meet the use of detectors with various wiring methods.

This system adopts a microprocessor as the control unit and high-precision sensors as the detection components, with high sensitivity and fast response speed. When the concentration of the gas to be tested detected in the environment reaches or exceeds the early warning alarm value, the controller immediately issues an audible and visual alarm to remind us to take safety measures in time and start the execution control unit to control and drive the exhaust or other peripheral equipment to prevent the occurrence of poisoning accidents, explosions and fires, thereby ensuring the safety of life and property.
