JTF-PH07A/TCM Compound domestic combustible gas detector

JTF-PH07A/TCM Compound domestic combustible gas detector(hereinafter referred to as gas detector), is used in domestic kitchens who using natural gas, which could be used to detect natural gas (methane) leakage, the over standard  of carbon monoxide concentration produced by incomplete combustion is over standard and ultra high ambient temperature.  When an alarm occurs, the detector sends out sound and light alarm signals,  and controls to close the valve and cut off the gas supply,  so as to prevent gas leakage and explosion accidents,  personal poisoning accidents and fire accidents.
