We all know that air is an indispensable part of our lives. The quality of air is affecting our body and mind, but the air is colorless and tasteless, we can't measure it with the eyes. At this time, we need an air tester to help to monitor the air quality.

Features:
LCD large screen, different font colors display different air quality, green 400-799ppm, yellow 800-1199ppm, orange 1200-1599ppm, red 1600-1999ppm, 2000ppm above four colors flash at the same time.
The product is compact in size and easy to carry. The ventilation holes in the rear not only accelerate the convection between the air and the machine, so as to achieve effective detection, but also provides fine heat dissipation effect.
The product does not need calibration, startup can be tested, accurate detection of carbon dioxide, used in greenhouse farming agricultural production, production warehouse, laboratory, family, etc.
Widely used and practical, used for epidemic preventions and control to detect the CO2 concentration in the population, so as to control the number of people and avoids the risk of cross-infection.
1200mAh large capacity battery for long working time, Type-C charging interface, easy charging.
