Description
QD8000 Intelligent gas detection controller is a multi-point monitoring gas alarm system , are used to test the concentration of the gas in the air, when the concentration of detecting gas reaches or exceeds the preset alarm value, the controller will alarm immediately to remind us and take safety measures, and start the actuator to control driving the exhaust or other peripheral equipment, to prevent accidents, poisoning, fire and explosion, so as to ensure the safety of life and property。
