HM-712D

Designed with LCD display, the HM-712D series combustible gas and carbon monoxide detector can detect the natural gas and carbon monoxide both. The double sensors design is professional and reliable. Supporting 9V backup Ni-MH battery for power supply, the product can still work even in case of power outage. After the alarm, it would reset automatically when the gas is dispersed.

Meanwhile, the combustible gas and carbon monoxide detector would make the inspection once every three minutes for ensuring the normal work. In the alarm state, it can output DC 12V instantaneous voltage to drive the electromagnetic valve which can cut off the gas source to make sure that the gas won't leak again. The product can also drive the fan to decrease the gas concentration instantly.
