Project Description

natural gas detector 

Product Name : Independent Gas detector






The product is wall mounted gas detector with high stability, It is used for detecting leaking gas. Advanced semiconductor sensor is adopted to ensure high stability and long life. It is convenient for mounting. The product is suitable for the safety of residential house, villas, hotels, markets, boarding house etc.

* Installation Mode: wall mounted




To test the installed detector while using independently, you can give some gas around in distance of 5cm to the gas convection holes by using un-ignition lighter.


Testing frequently may result in reducing the sensitivity of the detector. The alarm density of gas is set according with the criteria of GB15322.2-2005.The Detector will stop alarm and resume to the detecting state while the gas density reduced to lower than the alarm level.




Suggestion: the user must brush and clean the gas convection holes with a little cleanser every three months, and must retest the Detector after cleaning for preventing the cleanser into the Detector.




The Detector alarms while the gas density in air exceed the alarm level. The relative treatments as below:

1. Shut down the tube valve right away.

2. Open the window and make the air flow rapidly.

3. Extinguish all fire sources and do not use anything can make fire, e.g. lighters, matches, etc.

4. Avoiding open or close the power all kinds of electric equipment.

5. Check the reason of gas leaking, and notice the relative departments and professional persons in time.
