    1. Carbon monoxide detector with intelligent detection of multiple gases and accurate detection and responsive internal dual sensor, can detect carbon monoxide, smoke and other gases.
    2. Sound and light treble alarm loud sound and long service life.
    3. When smoke and co detector detects that the concentration of carbon monoxide in the air reaches the alarm setting value, the detector sends out.
    4. Smart smoke detector with sound and light alarm signal, LCD display concentration value, red light flashes quickly dual performance sensor.
    5. Effective detection of carbon monoxide smoke with high-performance sensors can quickly detect and alarm, intelligently create digital processing technology.
    6. Smoke alarms and carbon monoxide detectors have high stability, low power consumption, and reject false alarms. The buttons have self-test functions, which can self-check faults and prompt alarms.
    7. Combination smoke and carbon monoxide detector has short press the test/self-test button of the detector, when the red light flashes, the detector beeps, LCD displays the current gas concentration value, and the detector function is normal.

    Tips: What is carbon monoxide smoke detector?

    1. Carbon monoxide detector is an electronic device used to detect carbon monoxide. It can send out sound or light alarm when the concentration of carbon monoxide in the air exceeds the standard.
    2. The carbon monoxide alarm uses a carbon monoxide sensor to convert the concentration signal of carbon monoxide gas in the air into a weak current or voltage signal, and then amplifies the signal through one or two stages, and then sends it to the single-chip microcomputer for signal comparison and processing. Sound and light alarm signal, drive LED light, horn or buzzer.
    3. Carbon monoxide alarm can be divided into two types: industrial and household carbon monoxide alarms. Industrial carbon monoxide alarms are expensive, requiring very high precision, and small temperature and zero drift. In some special occasions, explosion-proof enclosures are often required. Industrial carbon monoxide alarms must use electrochemical sensors.
    4. Home co smoke detectors are mainly used in ordinary households, small entertainment venues, small factories and small chemical laboratories, etc. With a relatively small appearance and relatively low price.
