HM-712DSY

The HM-712DSY combustible gas and carbon monoxide detector can detect both natural gas and carbon monoxide leakage. It has a LCD display for showing gas type, battery power, and alarm concentration. The user can master all the data clearly at any time. Immune to the voltage instability, the product works on AC100-240V. It can also be powered by 9V backup Ni-MH battery.

Designed with nice appearance, the combustible gas and carbon monoxide detector is 118.5mm in length, 82mm in width and 43mm in thickness. It adopts the internationally UL certified electrochemical sensor for CO detection sensor, and utilizes the NEMOTO catalytic combustion type sensor for the natural gas detection sensor.
