> Product Function：

The working principle of a carbon monoxide detector: When an object burns, it will produce smoke and carbon monoxide. When the concentration of carbon monoxide reaches the alarm standard, the detector will sound an alarm, allowing family members to detect the danger in time. It can be placed in the living room, room, garage, car, tent, etc. It can be installed on the wall with screws or placed freely on the desktop.

1. The performance of the sensor and the detection system have been optimized, and a newly upgraded high-quality sensor detection head has been adopted. It has a longer lifespan, higher accuracy, and a lower false alarm rate.

2. The LCD concentration value is displayed in real time and will not turn off automatically. In standby mode, the value always shows 0 ppm. When the alarm concentration is reached, the light will turn on and the value will change.

3. Historical alarm record query function: After the device alarms, pressing the test button can query the highest value of the previous alarm. It will only display the record once. Pressing again will restore it to the initial value of 0 ppm.
