The QB10N fixed ethylene oxide gas detection alarm can effectively detect the concentration of flammable gases and prevent the concentration of toxic gases after gas leakage. A combustible gas alarm is composed of two parts: a gas alarm controller and a gas detector. The combustible gas alarm controller can be placed in the duty room and mainly controls various monitoring points. The combustible gas detector is installed in places where gas is prone to leakage. The core component of the gas detector is the built-in gas sensor, which detects the concentration of gas in the air. The gas detector converts the gas concentration detected by the sensor into an electrical signal, which is transmitted to the controller through a cable. The higher the combustible gas concentration, the stronger the electrical signal. When the gas concentration reaches or exceeds the alarm point set by the gas alarm controller, the gas alarm controller sends an alarm signal and can activate external devices such as solenoid valves and exhaust fans to automatically eliminate hidden dangers.

The QB10N ethylene oxide gas alarm detects gas concentration through natural diffusion and uses imported catalytic combustion sensors, which have good sensitivity and excellent repeatability; LED digital displays suitable for factory applications display the concentration value of leaked gases in real time, and immediately activate sound and light alarm signals or drive exhaust systems when the preset alarm point is exceeded; The international standard (4-20) mA signal can be directly connected to the factory DCS system, and the RS485 digital signal is connected to the factory upper computer; The instrument adopts embedded microcontroller technology, with simple operation, complete functions, high reliability, and reliable overall performance.

QB10N fixed ethylene oxide gas detection alarm, combustible toxic gas alarm, combustible harmful gas alarm, gas leakage concentration alarm, gas alarm device produced by Henan Chicheng Electric. The combustible and toxic gas alarm has obtained the fire product type approval certificate issued by the National Fire Electronic Product Testing Center, and has the production license for measuring instruments issued by the national quality and technical supervision department.

Chicheng QB10NFixed ethylene oxide gas detection alarm， The QB10N combustible and toxic gas alarm strictly follows the national standards GB12358-2006 "General Technical Requirements for Gas Detection and Alarm Devices in Workplace Environment" and GB15322.1-2003 "Point type Combustible Gas Detector with Measurement Range of 0-100% LEL", GB16808-2008 "Combustible Gas Alarm Controller". The combustible gas leakage alarm controller has a beautiful appearance, clear display interface, and simple operation. The product adopts a modular structure design for easy maintenance. The combustible and harmful gas alarm has two sets of passive relay signal outputs. One group is kept normally open and normally closed (exhaust output), and the other group is a three second pulse normally open and normally closed (valve output).
