Therefore, please keep away from such materials as alcohol cosmetics contain alcohol perfume, etc. ) cigarettes (containing carbon monoxide), smoke(containing acrylic acid) and fruits (containing ethyl alcohol) before detection.
5. It's better to close the windows and doors for 10 minutes at first before testing formaldehyde in bedrooms, sitting rooms and cloakrooms. The average value of various locations test data in a room is the average content of formaldehyde in the room
6. The detector adopts air free-flow diffusion sampling method. While the detector transfers from one room to another one, it takes a certain time to respond and the user needs to wait for 10 minutes to read the data.
