Carefor PT-01 Carbon Dioxide Detector

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 default temperature is Fahrenheit

Air Pollution

The Harm of Carbon Dioxide
The normal content of CO2 is 0.04%. When the concentration of CO2 reaches 1%, people will feel stuffy, dizzy, and palpitations. When it reaches 4%~5%, people will feel wheezing, headache, and dizziness, and when it reaches 10%, It will cause serious disorders of human body functions, cause people to lose consciousness, become unconscious, stop breathing and die. Carbon dioxide poisoning is a coma and cerebral hypoxia caused by people inhaling high concentrations of carbon dioxide. Generally, when the carbon dioxide content in the atmosphere exceeds 1%, people have mild poisoning reactions; when it exceeds 3%, breathing difficulties begin to occur; more than 6 %, it will be deeply poisoned and even die. Our Carefor PT-01 carbon dioxide detector uses laser sensors to accurately detect CO2, which can be used in homes, schools, gyms, offices and restaurants, help you to improve the quality of life.


The Harm of Smoke
The concentration of carboxyhemoglobin in the blood of a mildly poisoned person is between 10% and 20%, and severe headache, dizziness, nausea, vomiting, palpitations, vertigo, weakness of the limbs, lethargy, irritability, unstable gait, and need to leave in time In a poisoned environment, inhaling fresh air, the symptoms can be relieved quickly and gradually recover completely.

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.

Coy Stamm

such a nice device, the CO2 meter responds if I breath on it.. further it checks the temperature and humidity. Don't know how accurate off course, something to investigate. i out it together with other measuring devices and see that they give different values.. further it do responds on changes in the room, for example steam from induction cooking, it's a cute thing.

Mackenzie Raynor

Tester works well. Recommend.
