1:cheap gas detector 2:MCU control 3:for natural gas, lpg, coal gas 4:Easy installation 5:ISO9001:2008

cheap home-use ceiling mounted gas detector gas alarm  

 Feature:

1: Using independent air cavity technology, this can reduce the response time, improve the measurement accuracy, the buzzer can't interfere with sensor detecting .Gas inlet adopts "shutter" ,this can reduce dust and lampblack to sensor's direct influence 

2: Sound and light alarm,and automatically output signal, easy to control external equipment

3: MCU control

4: Film sensor designed with professional agency ,which can effectively avoid false alarm caused by the smoke and alcohol

5: Automatic sensor fault detection

6:After alarming and when gas concentration lower to alarm setup value , Detector will auto-reset ( gas valve manual reset )

7: Manual start output in the case of emergency

8:  Easy installation and using.

9:Temperature control (adopted ATMEL-USA technology) to avoid kitchen temperature rises up in a sudden.
