  • product description

Product concept


The HA-818D combustible gas detector (hereinafter referred to as the detector) is a highly stable semiconductor sensor, which has the characteristics of high stability and small sensitivity drift. It is used for indoor detection of flammable gas leakage to prevent the harm caused by gas leakage. It is widely used in households, hotels, apartments and other places where flammable gas is present for safety monitoring. Can detect natural gas, liquefied petroleum gas, artificial gas.


When the detector detects a flammable gas leak and reaches the alarm concentration set by the detector, the detector's red LED flashes and emits an alarm sound.

Installation Precautions


1. First determine that the gas to be detected is heavier or lighter than air, and gas heavier than air: liquefied petroleum gas, etc .; lighter than air: natural gas, artificial gas, biogas, etc.

2. Install the detector in a suitable place according to the weight of the gas.

When detecting gas heavier than air: install it 0.3-1.0 meters above the ground and within 1.5 meters from the air source; when detecting gas lighter than air: install it 0.3-1.0 meters below the ceiling and within 1.5 meters from the air source (See the figure below for details)
