Carbon Dioxide Meters
-
Product Highlights- 🏠🏠3 color smart alarm: designed with 3 stages of co2 concentration— normal stage (400-700 ppm), warning stage (700-1500 ppm), and dangerous stage (1500-5000 ppm). it will alarm you when the detected co2 concentration is beyond the safe value you customized.
- 🏠🏠usb rechargeable: a 2400 mah lithium battery is embedded inside the detector, we recommend using the device while charging. besides, it adopts a large and distinct lcd screen for easy data viewing. you can select ℃ or ℉ for temperature display based on your need.
- 🏠🏠3-in-1 multifunction air monitor: the air quality monitor can accurately detect the level of carbon dioxide(co2), temperature, and humidity. high precision internal sensors for a fast and accurate reading, are home or office indispensable equipment.
- 🏠🏠accurate results: adopted a high-precision infrared sensor and a built-in high-performance chip, which can accurately capture the weak current generated during the electrochemical reaction, to calculate the carbon dioxide measurement result. pressing three buttons simultaneously triggers the calibration function.
- 🏠🏠wide application: a hanging hole is designed on the back of the detector so that you can hang it up to the wall for easy viewing. the co2 detector is ideal for use in homes, offices, grow tents, wine cellars, and cars.

- Necessity of air quality monitor: carbon dioxide (co2) is not harmful to human body when it is low, but when it overs a certain amount, it will affect the breathing of humans (and other organisms). if serious, life is threatening. thus, we have to monitor the co2 content of air for keeping health.
- Air semiconductor sensor: 4-in-1 air quality monitor adpots intelligent air semiconductor sensor to test the temperature and humidity value of air. compare with the common sensor, it is more sensitive, accurately and stable.
- Easy to use: each turn on, co2 detector need to automatic calibration, so please put the air quality detector in a ventilated place, after 1-2 minutes calibrating, co2 tester can be used normally.
- Note: dear customer, compare with other co2 meters, please allow the differece (about ±50 ppm). after all, different co2 meters adopt to different ndir sensor, so their test result is exsit the difference. thanks for your understanding.
- Indoor co2 monitor: compact size body with hollow back design for carring and airflow. big colorful lcd digital screen for people easy to identify and read. not only monitoring the co2 content, also can test the temperature & humidity. air quality monitor is keeper of family health, perfect for home interior, such as living room, baby room, classroom, office and which c...
- Advanced ndir technology: mini co2 meter uses high precision ndir sensor technology to detect carbon dioxide content accurately and quickly. and it can hazard assessment, when co2 of air exceed the setting alarm value(alarm value: 1000 ppm), it will warn to remind people to open the window or turn on air purifier for keeping balance of air.
