Product Description
This product is a multifunctional air quality detector that detects 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 formaldehyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display.


Considerations
Please read the instructions carefully before using this device.
Please calibrate the device outdoors before use for most accurate results.
Please keep the manual handy for quick reference and troubleshooting.
Precautions
Avoid covering the air intake areas during use to avoid inaccurate measurements.
Avoid use of solvents to clean the product as residual fumes will skew air quality readings.
Avoid water or other liquids near the product to avoid electrical damage.
Do not allow unauthorized modification or repair of this product.

HCHO (formaldehyde) ideal range: <=0.10 mg/m3 (0.08 ppm/m3)
TVOC ideal range: <= 0.6 mg/m3 (0.45 ppm/m3)
The formaldehyde alarm threshold can be set to 0.1, 0.3, or 0.6 mg/m3. If levels of HCHO exceed the set formaldehyde alarm threshold, the device will alarm with short beeps.
