When the concentration value is higher than 30 ppm, the screen lights up and displays the value so you can check the PPM value at any time.



The carbon monoxide detector is equipped with an LCD display for easy real-time reading of values (ppm) and audible and visual alarms. When the concentration exceeds a certain level, the alarm sounds 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 property.
