This can be used to test and display PM2.5, PM10, carbonic oxide, carbon dioxide, TVOC, HCHO, and AQI at the same . Uses high-precise semiconductor , with high sensitivity, superior interference resistance ability, stable working performance, with low consumption. And also have and date display and function. APP control, suitable for agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, business offices, and etc.

Features:
Portable Size:
This is small in size and you can use it on your desk without taking too much desk space, also easy for you to carry.
7in1 Quality Tester: This can be used to test and display PM2.5, PM10, carbonic oxide, carbon dioxide, TVOC, HCHO, and AQI at the same . And also have and date display and function.
Semiconductor Sensors: Uses high-precise semiconductor sensors, with high sensitivity, superior interference resistance ability, stable working performance, with low consumption. Real- detection, automatic refresh data, with multi-use.
TFT Color Display: This quality with a large TFT color display for you to see the detecting data more clearly, you can get the results easily.
AQI Quality Level Indication Function: The ball will change color according to the quality index, and allowing you to more accurately and more graphic know the current conditions.
Cellphone APP Control: Search for Tuya APP in the application program, the device will enter the pairing state after the firsttime opening, and you can view the specific data on the APP after completing the connection. (Because it takes to upload data, it is normal for the APP data to deviate from the real- data of the .)
Strong Heat Dissipation: Hundreds of ventilation holes reserved on the housing not only accelerate the convection between the and the machine, thereby realizing effective detection, but also provide a fine heat dissipation effect.
Wide Applications: Suitable for agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, business offices, and etc.
