The natural gas alarm is designed to continuously monitor the methane concentration. Adopting catalytic type gas sensor and advanced electrical technology, it responds quickly and becomes highly sensitive with stable performance and low false alarm. Once the surrounding methane concentration reaches the alarm threshold, it will quickly send a visual and audible alarm signal to remind the user to take immediate action.

· High performance sensor, send alarm signal timely
· Operate stably and identify gas type effectively
· Intelligent linkage to close the pipeline valve and start the exhaust fan
· A built-in high volume buzzer, 70 dB (A) at 1 m (3.28 ft)
