Air Quality Index (lower left corner of the second interface) is for reference only. Formaldehyde data at the first interface.
Please see the formaldehyde value three minutes after the boot. Co2 data is updated in real time. Detection should not be close to the
detector, the human body to produce high concentrations of Co2 interference will interfere with detection.
Co2 is preferably calibrated once every month or every two months when tested. The calibration method is a continuous boot 7 * 24 hours.
TVOC sensor work need to warm up for 10 minutes, the work of the sensor within the 200-300 degrees Celsius, the surface will be hot. Is
the TVOC sensor in the normal work, (TVOC sensor itself limited to the technical level of development restrictions, still can only reflect the

Formaldehyde attention to the following points:
1)Temperature. Must be higher than 18 degrees Celsius. Formaldehyde at 18 degrees Celsius began to evaporate.
2). Space needs to be sealed for 24 hours, which is conducive to the loss of formaldehyde volatilization.
3)Eliminate disturbing gas during confining. Such as alcohol, perfume. Make-up water and other fragrant fruit.
