Features:
Compact in size, lightweight and portable, easy to take out and carry around with you.
Adopts quality intelligent chip for fast response and more accurate measurement of CO2 in air, with high working performance and high accuracy.
Uses high accuracy semiconductor sensor, high precise temperature and humidity detection, with fine interference resistance ability, stable working performance, with low power consumption.
Large display, you can see the electricity quantity, CO2 value, TVOC value, HCHO value, temperature, and humidity clearly.
Multifunctional design, with real-time detection, automatic refresh data, and self-calibration functions.
Equipped with air quality level division function, 4 different words correspond to different air quality levels, allowing you to more accurately and more graphic know the current air conditions.
​The multi-channel air convection design enables efficient detection due to the high convection between the air and the machine, while also providing a fine heat dissipation effect.​
Widely applications: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, business offices, and etc..
