Independent Carbon Monoxide Detector with Backup Battery

The HM-721EHS-BT independent carbon monoxide detector is powered by battery. It adopts the intelligent circuit design, and has the fault self-diagnosis function. When the carbon monoxide concentration gets to the alarm threshold, the product would emit the sound and flash alarm with the alarm sound pressure of 85dB/3m. The design of battery compartment on the top of the product allows for easy and convenient battery replacement. Meanwhile, the product consumes low power. Two 1.5V AA batteries can support the work of the product for more than 3 years. And the special design for battery compartment can avoid the user forgets to load the battery.

The independent carbon monoxide detector utilizes the electrochemical sensor. It is characterized by high sensitivity, strong conformability, low power consumption, and stable performance. After the product raises the alarm, the mute button can let the product enter mute state. Compliant with the international standard of EN50291, the product is shockproof and can be mounted into the vehicle for detecting carbon monoxide in the vehicle to provide protection.
