China Gas Leakage Detector Gas Detector Fire Alarm

Gas Leakage Detector: Self-detecting, no wrong report, and reliability. Can be used with the alarmsystem to send the sign to thecontrol panel if detecting density with time reaches the limit figure required as below and then it alarms and the alarm control panel auto-dials the presetting telephone or mobile phone. It is designed for a wide ranCrushing & Culling Machine ge of residential where reliablegas leakagedetection is required.
Wired/ Independent use optional.Features:
