Carbon Monoxide Detector with LCD Display

The HM-712ESY series carbon monoxide detector is furnished with the LCD display screen for showing the alarm concentration. It employs the NEMOTO electrochemical sensor. Working on the wide voltage of AC110V-240V, the product won’t be affect by the instable voltage. It also supports the use of rechargeable backup battery. When the battery power is insufficient, the product can remind the user of that. When the product is in alarm state, it can drive the fan to disperse the gas, and drive the electromagnetic valve to close the valve to stop gas leakage. Additionally, the carbon monoxide detector is approved by the standard of EN50291.
