Utilizing advanced infrared (NDIR) sensor technology for the CO2, Electrochemistry sensor for the HCHO and TVOC. Compare with the common sensor, it is more sensitive, accurately and stable.
●【User-Friendly Operation】 Simply press and hold the "Power" button for 3 seconds to turn on or off the indoor Air Quality Detector. Once turned on, it will automatically begin detecting. The default temperature unit is Celsius (℃), but if you prefer Fahrenheit (℉), simply press and hold the "Power" button for 1 second to switch temperature units.
●【Two power supply options】 Our indoor air quality monitor is equipped with a built-in 1200mAh rechargeable lithium battery and a USB charging cable. It can last up to 8 hours on a single charge, making it suitable for portable use. If used for an extended period of time in a fixed location, it is recommended to insert the USB charging cable to ensure uninterrupted operation. (Note: Data may be less accurate when using it while charging or when the battery is low. Charging plug not included)
●【Wide Application】This portable intelligent home air quality meter can detect air quality in bedrooms, living rooms, kitchens, cellars, cars, grow tents, offices, schools, hotels and more. it can be placed on the desktop for easy viewing, is an ideal indoor air quality detector for our lives.
●【Special note】In single-channel infrared detection technology, CO2 data will inevitably shift after transportation or use for a period of time, so manual calibration is required. If the CO2 data deviation is found to be large after the first startup, calibration is required. After the device is powered on, place it outdoors or near a window for more than 10 minutes. Press the multi-function button 3 times in succession and the calibration will be completed after a beep sound.

With its convenient design, you can monitor the environment at any time and it efficiently measures five crucial indexes for evaluating air quality.
- Convenient operation
Simply press and hold the "Power" button for 3 seconds to turn on or off the indoor Air Quality Detector. Once turned on, it will automatically begin detecting. The default temperature unit is Celsius (℃), but if you prefer Fahrenheit (℉), simply press and hold the "Power" button for 1 second to switch temperature units.
- Scientific layout and rational design
The Air Quality Tester is designed with 4 holes to increase air circulation and improve heat dissipation and testing accuracy.
- Two power supply options
1.Our indoor air quality monitor is equipped with a built-in 1200mAh rechargeable lithium battery and a USB charging cable. It can last up to 8 hours on a single charge, making it suitable for portable use.
2.If used for an extended period of time in a fixed location, it is recommended to insert the USB charging cable to ensure uninterrupted operation. （Note: After inserting the power, the device will have a slight heat, causing the measurement temperature to have a deviation of ± 2 ° C. If you want to measure the accurate temperature data, please unplug the charging cable and wait ten minutes before testing again.）
Why do we use CO2 air quality detectors?
|
|
|
|
|---|---|---|
|
With air conditioners, fireplaces and heaters, its still warm inside even when its snowing outside, but carbon dioxide (CO2), a metabolite that builds up indoors, is the culprit behind our lack of productivity. |
In a crowded office, CO2 levels can easily exceed 1%, leading to irritability and heart palpitations. |
In a closed bedroom, the concentration of carbon dioxide (CO2) accumulated overnight is often higher than 2%, people will feel short of breath, anxiety, and sleeplessness. |
In fact, the carbon dioxide (CO2) content in the air is only 0.03%, while the CO2 content in our surroundings is hundreds of times higher!
How to deal with the hazards of high carbon dioxide (CO2) concentrations?
Sometimes we stay indoors for a long time, the space is relatively closed, air circulation is very poor, a long time will feel irritable, stuffy, difficult to concentrate. This is because changes in carbon dioxide (CO2) levels in the air can affect a persons ability to react and make decisions.
- First of all you need to know the level of carbon dioxide in your environment, otherwise there is no way to know if you are in a good air environment, using an air quality detector to test the level of carbon dioxide in the air.
- When you know the level of carbon dioxide is too high, you can remind you to open the windows to ventilate the room, timely introduction of outside air into the room, and the indoor dirty air out of the outdoor. Always keep the indoor air healthy to protect you and your familys health.

Carbon dioxide (CO2) concentration standards and human perception
The concentration of carbon dioxide in the air is also a measure of clean indoor air.
- 350-700ppm: the air is clean and people feel comfortable.
- 700-1000ppm: is considered normal, and is considered ordinary air, but some sensitive people may have a bad feeling.
- 1000-1500ppm: the air is at a critical stage, and many people will feel uncomfortable.
- 3000-4000ppm: it will cause people to deepen their breathing and experience symptoms such as headaches, ringing in the ears, and increased blood pressure.
Q: How to adjust the degree Celsius to Fahrenheit?
A: The default temperature unit is the degree Celsius (° C), but if you prefer Huas (℉), just press the "power" button for 1 second to switch the temperature unit.
Q: Why is the data of the C02 of the air quality detector significantly high? For example, much higher than 400ppm.
A: In the single -channel infrared detection technology, CO2 data will inevitably offset after transportation or use, so manual calibration is required. If the CO2 data deviation is large after the first start, calibration is required.
Calibration method: After the device is powered on, it is placed outdoors or near the window ventilation for more than 10 minutes. Press the "Power" key 3 times in a row, and complete it after "di ~".
Q: Why does it have no reaction to insert the power cord when charging?
A: When the device is charged in the shutdown state, the device is already charging when you insert the power cord normally. Although there is no indicator prompt on the screen, please dont worry that it is already charging.
When the device is charged, the battery icon in the upper right corner of the screen will flashes and jumps, and it will stop beating when it is full.
Q: Why is the temperature data higher than the actual?
A: After plugging in the power supply, the device will heat up slightly, resulting in a deviation of ±2°C in the measured temperature. If you want to measure accurate temperature data, please unplug the charging cable and wait 10 minutes before testing again.
Q: How long can it be used when fully charged?
A: It has a built-in 1200mAh rechargeable battery, which can be used for 8 hours after a single charge, making it suitable for portable use. If it needs to be used in a fixed location, it is recommended to plug in the USB charging cable to ensure uninterrupted operation. (Temperature data may be inaccurate during charging)
