DESCRIPTION
Features:
- Carbon dioxide detector: Smart carbon dioxide value tester gas analyzer uses air semiconductor TVOC sensor to monitor temperature and humidity of air quality.
- It is a high-quality air quality detector, using a good-quality electrochemical detection module, with good accuracy, stable performance, strong anti-interference ability, low consumption and long service life. Accurately detect carbon dioxide. The large screen displays power , CO2, temperature and humidity.
- Adopt electrochemical detection module of high quality, with good accuracy, stable performance, strong anti-interference ability, low consumption and long life of the cabinet.
- The product does not need calibration, it can be tested after booting, and it can accurately detect carbon dioxide.
-The large screen displays the power, CO2 value, temperature and humidity.
- Equipped with a large screen, different font colors display different air quality, green 400-450ppm, blue 451-700ppm,Purple 701-1000ppm, yellow 1001-2000ppm, red 2001-5000ppm.
- Hundreds of ventilation holes at the rear not only accelerate the convection between the air and the machine, thereby realizing effective detection, but also provide a good heat dissipation effect.

Precautions for the use of sun detector:
The correct way to use the detector for the first time:
1.5-in-1 starts for 1 minute, and then restarts for 13 seconds to return to use again.
2.3-in-1 startup is generally the highest. The effective time is when the power is completely consumed for the first time, and the startup is restarted. The environment and air are affected by various factors. Please refer to the usage method.
