Test formaldehyde method: measure with a formaldehyde kit, first close the doors and windows, pour out the post-white reagent, seal it in the room for 30 minutes, then pour out the brown reagent, leave it for 10 minutes, and finally compare it with the color card. The formaldehyde value of the room can be measured.
We all know that new furniture or cars, even clothes, contain formaldehyde, which will be bad for our health after absorption. So how do we test formaldehyde? The following is a brief introduction to the testing methods.
First seal the room and close the windows, doors and windows.
Then open the formaldehyde reagent box, and pour all the white bottle reagents into the absorption box, as shown in the figure below.
Next, we will absorb the lid cover, until completely dissolved substances.
After half an hour, the brown reagent is completely poured into the absorption box, gently shaken, then closed and left for 10 minutes.
The color card is then compared and the formaldehyde contained in the room is measured.
