Product Description LPG Gas Alarm Detector is a new standalone AC powered plug-in combustible gas detector to protect you and others from the dangers of combustible gas(natural gas, LPG and LNG). The detector is with LCD digital screen continuously displays the level of explosive gas (if any) the alarm is sensing. The detector adopts MCU processing technology with a long life, convenient installation and high reliability. Besides, it completes with a special circuit that control the advanced semiconductor sensor and catalytic sensor’s efficiency level, and signals any possible fault. HD1100A alarm is easily installed in any of your AC wall outlets or can be mounted higher on the wall using the power cord. Benefits:
