Using independent HCHO and TVOC air detection probe
Temperature and Humidity value display
HCHO testing value Exceeded alarm and Alert alarm
Air Quality Index, showing the current AQI value
Support rechargeable high capacity lithium battery,long time working
When you press the multi-function button, the instrument automatically enter the boot mode. See below:
1) P M2.5 display area, showing the current PM2.5 value.
2) Formaldehyde display area, showing the current HCHO value.
3) Air Quality Index, showing the current AQI value.
4) Battery symbol, indicating battery indicator and charging indicator.
5) Temperature display area, showing current temperature.
6) Humidity display area, showing the current humidity
7) TVOC display area, showing the current TVOC value.
( Remark : When each booting up, there will be 200 seconds on screen automatic countdown. This is the formaldehyde preheating process. HCHO and TVOC will not display real time value until 200 seconds preheating process is completed)
Formaldehyde correction method:
When the formaldehyde content is not in the normal range, the machine need to be calibrated. Correction method: Put the device into a place of good air quality ,turn it on , let it aside for 5-10 minutes,then quickly click the power button twice . you will see the HCHO value is 0.000 and TVOC value is 0.000, the calibration is completed. After correction well, go to do the next test.

Q: Why do I need to calibrate?
A: The working mode of our products is to use the air sampling of outdoor formaldehyde-free gas as a benchmark, and then take the indoor formaldehyde content as a comparison. Therefore, the new machine product is not used for a long time, and it is necessary to detect a large change in the ambient temperature. Calibration and re-testing, the value of this calibration has a great correlation with the accuracy of subsequent tests. The calibration environment must avoid chemicals, perfumes, paints, cigarettes, air fresheners, alcohol and other chemical pollutants to avoid damage to the sensor.
