Carbon monoxide detector with LCD screen, CO detector, 85 dB audible alarm, carbon monoxide detector with carbon monoxide sensor

Audible and Visual Alarms: Carbon monoxide detectors use highly sensitive sensors. The concentration of carbon monoxide in the ambient air is thus continuously measured. When the concentration reaches the set threshold, the detector emits an audible alarm and a flashing indicator light alerts you. Robust Sensor Operation: Made from durable, high-quality materials, this carbon monoxide detector features a high-performance, sensitive, and robust sensor. Its operating temperature range is from 5°C to 40°C, and its optimal relative humidity is between 20% and 90%. LCD Display of CO Concentration: Carbon monoxide is a common respiratory poison, undetectable by the senses. Thanks to the LCD screen, you can read and monitor its concentration at any time to avoid potential danger. Battery operated: This carbon monoxide detector operates on replaceable batteries (2 x 1.5V AA). The built-in battery ensures long operating time. An audible signal every 30 seconds indicates that the batteries are low and need replacing. (Batteries not included.)
