The S7300 series gas alarm controller is a multi-point monitoring gas alarm developed by our company. This system adopts a microprocessor as the control unit and high-precision sensors as the detection transmitters, featuring high sensitivity and fast response speed. When the concentration of the gas to be detected in the environment reaches or exceeds the preset alarm value, the controller immediately emits audible and visual alarms to remind us to take safety measures in time and activates the execution control unit to control and drive the exhaust or other peripheral devices to prevent poisoning accidents, explosions and fires, thereby ensuring the safety of life and property.
