Carbon Monoxide Detector, Carbon Monoxide Detector with LED Display (Ppm Value Always Visible) and 85 DB Acousto-Optical Alarm.

【Mini Carbon Monoxide Detector】 is equipped with an LCD display for easy, real-time reading of PPM values and an audible and visual alarm. When the concentration exceeds a certain level, the alarm remains constant and the red light flashes. You can quickly and clearly understand the ppm concentration and take appropriate measures to effectively protect your personal safety and the security of your property.

【Carbon Monoxide Detector】When the carbon monoxide concentration reaches 100 ppm, the alarm is immediately activated, the red light flashes, and the audible alarm sounds simultaneously. The loud 85dB tone can attract your attention more quickly. (Note: A short press of the button manually disables the alarm sound.)

【Widely Used Carbon Monoxide Alarm】Adopting a high-precision electrochemical sensor, it can quickly detect carbon monoxide gas. It can be used in the kitchen, bedroom, bathroom, garage, while camping, and other places.

【How to Use the Carbon Monoxide Alarm】Powered by 3 AAA batteries, it automatically turns on after charging, then enters operating mode after a 30-second countdown. The ppm value is visible at all times.

【Alarm Self-Test】To check if the product is effective, you can briefly press the button once for the self-test. If the screen does not display a value, it means the battery is depleted, reminding you to replace the battery in time. (Note: The battery can remain in standby mode for 10 months; the audible and visual alarm will cause rapid power loss.)
