About this item

【2 in 1 CO2 Detector】 Neoteck 2 in 1 CO2 detector monitors the concentration of carbon dioxide and TVOC in the air in real-time. Equipped with a high-precision sensor, the data is updated every 1 second. Now you can manually switch the display between CO2 and TVOC readings with ease. The detectable CO2 range is 430~5000PPM with an accuracy of ±50��賾, providing you with reliable and accurate data to protect your health, comfort, and that of your family
【Visual & Audible Alarms】Portable CO2 monitor intuitively indicates the current environmental status through the flashing of color blocks and buzzer alarm（alarm sound can be turned off）, reminding you to improve ventilation in time. Green is good, yellow is slight, orange is moderate and red is serious. When the detected concentrations of carbon dioxide and TVOC reach a certain level, the buzzer will sound an alarm
【Adjustable Brightness and Sound】Neoteck carbon dioxide alarm also features brightness and sound adjustment functions. You can choose from 3 screen brightness levels: dark, moderate or brightest according to your needs, ensuring you can see the display clearly in any lighting condition. Additionally, you can choose to enable or disable the sound. When the sound is turned off, all alarm sounds will also be turned off, allowing you to use it in a quiet environment without disturbing others
【10 Hours Battery Life】 Carbon dioxide meter built-in 700mAh rechargeable battery, takes only 3 to 4 hours to fully charge. With 6-7 times of use per day, the battery lasts for over 20 days, so you don't need to recharge it as frequently. The CO2 detector features an auto-off function that activates after 5 minutes of inactivity to conserve battery. Importantly, you can now easily cancel this auto-off timer at any time after startup (no need to restart the device)
【Compact and Portable】Mini CO2 detector features a compact portable design, with dimensions of only 80mm*47mm*20mm, and it also comes equipped with a special lanyard for easy carrying or hanging. Whether during outdoor activities like camping and exploring, or in confined spaces such as homes, hotels, and cars, you can monitor CO2 and TVOC concentrations at all times to ensure your safety and health
【NOTE】 As a matter of fact, CO2 is a natural component of the air. Outdoor: approximately 400-420ppm (it may be slightly higher in cities). Indoors: If ventilation is poor (such as in offices or classrooms), the concentration may rise to 1000-2000ppm or even higher, which may affect recognition knowledge capacity (ASHRAE suggests maintaining it at <1000 ppm indoors). Below 400 ppm is a normal air component, no effect on our human. Our detector is based on this as the calibration value, and the value below 400ppm is not displayed

Product Description

Clear Air: CO2 Detector for Healthier Spaces!

Neoteck CO2 detector is used to monitor the level of air quality, primarily the concentrations of CO2 and TVOC in the air. By assessing the levels of these volatile organic compounds, you can evaluate the overall indoor air quality.

CO2 Detection Range is 430 to 5000 ppm, with an Accuracy of ±50 ppm!

Neoteck carbon dioxide detector is equipped with a high-precision sensor that can simultaneously monitor the CO2 and TVOC values. The CO2 range is 430 to 5000 ppm, and the TVOC range is 0 to 2.000 mg/m3. Data is updated every 1 s, and the CO2 and TVOC values automatically switch every 5s.

Why can't it detect CO2 concentrations below 400ppm?

CO2 is naturally present in the air due to processes like photosynthesis and respiration. Outdoor levels range from 300 to 420 ppm, while indoor levels are around 400 ppm. Our CO2 meter ignores values below 400 ppm as they are safe and usual.
Why does a 120s countdown appear each time it powers on?

A 120s preheat ensures more accurate readings.
What to do if it maxes out upon startup?

Long-pressing the calibration button to restore normal levels.
Why it has been maintained at a similar figure display, even if the concentration changes do not change?

This situation can be adjusted in several ways:

1. Take it to the outdoor, the value will change normally, our chip is 2s refresh data;

2. Calibration opeartion to restored to the value around 400-430 PPM.

CO2 Detector Shows Environmental Status Via Color Blocks and Buzzer Alarm

In excellent range, the green color block flashes slowly. In mild range, the yellow color block flashes slowly. In moderate range, the orange color block flashes and the buzzer sounds "BB...BB..." twice. In severe range, the red color block flashes and the buzzer sounds urgently "BBB...BBB..." twice

NOTE:The Alarm Sound can be Toggled On or Off

Portable 2 in 1 CO2 Detector with a built-in 700mAh rechargeable battery. It only takes 3-4 hours to fully charge and can be used continuously for 11 hours. Additionally, it automatically shuts off after 5 minutes of inactivity to help extend battery life.

CO2 Monitor Comes with A Dedicated Lanyard for Easy Carrying and Hanging

You can choose from three screen brightness levels—dark, medium, or brightest—to ensure clear visibility of the display in any lighting condition.
