First of all, it is difficult to test the concentration of formaldehyde. Generally, the so-called formaldehyde tester on the market actually measures VOC. To check whether it is a test for VOC, there is a very simple way: open your mouth continuously to the test port of the test instrument According to different sensitivity, the tester’s reading will rise rapidly, which shows that the tester is not actually for formaldehyde, but VOC. Secondly, the temperature and humidity of the room will have a great influence on the measured value of VOC, so it is best to measure under the condition where temperature and humidity do not change for greater accuracy.
