3in1 CO2 Temperature Humidity Monitor Infrared Semiconductor Multifunctional Air Quality Detector

Features:
Uses infrared semiconductor sensors, with high accuracy, stable performance, can accurately detect carbon dioxide value.
Adopts air convection design, which can provides more accurate detection results, and the detection-range is from 400ppm to 5000ppm.
Large color digital display, you can see the real time carbon dioxide concentration, time, temperature and humidity data clearly.
4-color circle design, different colors corresponding to different air quality, suitable for office, family, and other occasions.
0-799ppm the green color will flash, 800-1199ppm the yellow color will flash, 1200-1599ppm the orange color will flash, 1600-1999ppm the red color will flash, above 1999ppm 4 colors will flash.
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..
