of May 2024

  1. Product Highlights
    • 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.
