Carbon monoxide detector, carbon monoxide detector with LED display (ppm value always visible) and 85 dB acoustic-visual alarm.

【Mini Carbon Monoxide Detector】It features a "liquid crystal display for easy, real-time reading of values (PPM)" and an "audible and visual alarm." When the concentration exceeds a certain level, the alarm remains unchanged and the red light flashes. You can quickly and clearly understand the concentration in ppm and take appropriate measures to effectively protect your personal safety and that of your property. 【Carbon Monoxide Detector】When the carbon monoxide concentration reaches 100 ppm, the alarm is activated immediately, the red light flashes and the buzzer sounds simultaneously. The high tone of 85 dB can attract your attention more quickly. (Note: A short press of the button can manually silence the alarm sound.) 【Widely Used Carbon Monoxide Alarm】Adopting a high-precision electrochemical sensor, it can quickly detect carbon monoxide. Can be used in the kitchen, bedroom, bathroom, garage, camping, and more. It has passed the EN50291 safety certification, ensuring reliable quality. 【How to Use the Carbon Monoxide Alarm】 Powered by 3 AAA batteries, it automatically turns on after charging and then enters operating mode after a 30-second countdown. The ppm value is visible at any time. 【Alarm Self-Test】 To check whether the product is effective or not, you can briefly press the button once for a self-test. If the screen does not display the value, it means the battery is low, reminding you to replace it in time (Note: The battery can be kept in standby for 10 months; the audible and light alarm will cause rapid loss of power).
