This is a kind of quality air quality detector, which uses high accuracy sensors, with stable working performance. Large digital display, you can see the carbon dioxide concentration, real time temperature and relative humidity data clearly. Widely applications: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, etc.. You can have a try.

Features:
Uses high accuracy sensors, with stable working performance, can accurately detect carbon dioxide value.
Adopts air convection design, which can provides more accurate detection results, and the detection ranges from 400ppm to 5000ppm.
Large digital display, you can see the carbon dioxide concentration, real time temperature and relative humidity data clearly.
Colorful indicator light, the color grading indicates the air quality and temperature and humidity level, which can be known from a distance at a glance.
With 5 gears of brightness manual adjustment and brightness automatic adjustment function, and which can be on/off according to your demands.
Strong anti-interference ability, low consumption and long service life.
The product does not need calibration, it can be tested after booting, and it can accurately detect carbon dioxide.
Hundreds of ventilation holes reserved on the housing not only accelerate the convection between the air and the machine, thereby realizing effective detection, but also provide a fine heat dissipation effect.
Widely applications: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, etc..
