Multifunctional 3in1 CO2 Meter Digital Temperature Humidity Tester Air Quality Monitor with Time Date Electric Quantity Display Function

Features:
Uses NDIR s-ensor, 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.
3.5inch large color LED display, you can see the carbon dioxide concentration, temperature and humidity, electric quantity, time and data clearly.
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..
