Household Air Quality Detector Multifunctional CO2 Tester with Carbon Dioxide PM2.5 TVOC HCHO Value Electricity Quantity Temperature Humidity Display Backlit LCD Color Screen Self-calibration with Alarm Function

Features:
Compact in size, lightweight and portable, easy to take out and carry around with you.
Uses high accuracy semiconductor sensors, with stable working performance, can accurately detect carbon dioxide value.
Adopts electrochemical detection module with stable detection performance, anti-interference ability, low consumption and can provides long service time.
Large LCD color display with backlight, you can see the electricity quantity, CO2 value, TVOC value, HCHO value, temperature, and humidity clearly.
Real-time detection, automatic refresh data, with multi-use.
The product does not need calibration, it can be tested after booting, accurate detect and with sound-light alarm function.
Equipped with air quality level division function, 4 different colors correspond to different air quality levels, allowing you to more accurately and more graphic know the current air conditions.
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.
Wall-mounted design, it reserves two hung holes on the back of the machine, which makes it applicable to more scenarios and applications, with strong practicability.
Widely applications: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, business offices, and etc..
