Before an open flame appears, CO will be produced. After carbon monoxide is inhaled, it will be combined with hemoglobin in the body. After carbon monoxide is inhaled with air, it enters the blood circulation through the alveoli. Proteins (such as myoglobin, cytochromes of divalent iron, etc.) form the reversible binding.
Our air quality monitors for home perfectly fit your needs
High-Precision Data range: Working Temp:14°F-104°F(±33.8°F), Indicator lights, simulation bars and facial expressions indicate multiple air quality levels. Due to the high sensitivity of our product, please charge the product before use and place it in a ventilated place for about 24 hours, let it do self-calibration, and then use it.
Indispensable for testing air quality: The air detector is a professional air quality monitor.It uses non-dispersive infrared (NDIR) CO2 meter monitors carbon dioxide, temperature and humidity and smoke alarm functions.
Rechargeable Battery: When charging with the Micro USB that comes with the instrument, please use a power adapter with a specification of "5V-1A". In general, it takes about 3 to 4 hours to fully charge the batter
Occasions: It is suitable for living room, bedroom, baby room, meeting room, library and other various places. Exquisite appearance, simple design, light weight and easy to carry
Instructions for use
The Co2 reading and light indicator display: 0.-499PPM is shown as a green bar 500-999PPM shown in yellow, 1000-1499PPM is shown in orange, 1500PPM and above is shown in yellow displayed in red.
When the C02 reading reaches l000ppm. the device will beep twice. If it exceeds l0OOppm, the device will start to alarm continuously for 20 seconds. To silence the alarm. hit the Power button on the unit or touch the (Alarm shutdown. And the alarm will automatically turn off when the value is lower than1000ppm or after 20 seconds. If the C02 reading exceeds 2000ppm,the device alarm will sound again for 20 seconds. And It will be turned off when the value is lower than 2000pprn. When the C02 reading exceeds 4000ppm, the device buzzer sounds Du Du Du Du Du continuously every 20 seconds.
The smoke alarm buzzer continues for 2 minutes. To silence the smoke alarm, hit the Power button on the device.Or it will silence when the reading i below the threshold limit.
This product includes a rechargeable battery. The battery level can be accurately displayed on the screen: 25%, 50%, 75%, and 100%. When the battery level is lower than 1%. the monitor will sound didi for 20 seconds. And it only sounds “didi six times in one minute. The device will automatically Power on when it is charging, It takes about 4 hours to charge. The fully charged battery would last 6-8 hours

The Harm of Smoke
For the safety of your family, you need a carbon dioxide detector with smoke alarm to detect the air quality at home
The United States stipulates that the eight-hour average carbon dioxide concentration in the workplace cannot exceed 0.5% (5000 ppm). Animal experiments have shown that exposure to this condition for eight consecutive weeks can cause a decrease in bone density and kidney calcification. Other studies have shown that even at a concentration of 0.1% (1000 ppm), exposure for 2.5 hours can significantly reduce cognitive ability, which may be related to the increase in cerebral blood flow with carbon dioxide. Research in office white-collar workers shows that compared with 500 ppm, white-collar activity and information useability are reduced when the carbon dioxide concentration is 1000 ppm.
FUNCTION/OPERATION
1. Press the Power button and hold for 2 seconds to turn on
2. The corresponding temperature, C02 concentration, and humidity can be quickly detected within 5-7 seconds.
