Product Description
This product is a multifunctional air quality detector that detects CO2 (Carbon dioxide),Formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC), Particulate Matter <2.5 micron-sized particles (PM2.5/1.0/10), Temperature, and Humidity with clock and record function. As a scientific air quality detection device, it combines multiple air sensors with a built-in fan to allow real-time monitoring of CO2 (Carbon dioxide),Formaldehyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.

Features:
-4.3″ color liquid crystal display (LCD), 320×240 pixels
-Test variables: CO2,PM2.5/1.0/10, formaldehyde, TVOC, temperature, humidity
-Large 2000mAh capacity Lithium battery
-On-board fan to draw in ambient air for more accurate real-time results
-5V Micro USB charging
-Low battery warning

TVOC ideal range: <= 0.6 mg/m3 (0.45 ppm/m3)
The formaldehyde alarm threshold is 0.1, If levels of HCHO exceed the set formaldehyde alarm threshold, the device will alarm with short beeps.( if you want higher  formaldehyde alarm threshold, it is also possible for us to change it on software . if ou want to cancel alarm beeps ,it is also possible . )

About Charging
When low battery icon is displayed, the device needs to be charged. Insert the included or another compatible micro USB charging cable into the device. Attach the other end to a USB DC charger (such as a smartphone charger) that outputs DC 5V at >=1000mA. Fully charge for at least 2-3 hours before use. Avoid charging with a USB computer port which only outputs 500mA.
