Several problems of home air detection

  The following points need to be known in home indoor air detection: (1) know how to arrange points? Should we measure one room or all rooms? If the area of a single room in the home is not more than 50 m2, one point will be set for each room, that is, one point will be set for each room; If the living room is 50-100 m2, two points need to be arranged in the living room
If it is a new decoration or a new house, it is recommended that each room be tested
After all, the pollution of the new decoration is relatively large; If it is not a newly decorated or new house, it is recommended to measure each bedroom and living room as well as the kitchen, where people often stay, and the bathroom
You can choose whether to measure or not
(2) What are the air detection items at home? Generally, it is to measure the five conventional items
If there is marble or granite at home, it is still to measure radon (3) when is the air detection accurate? The data measured at any time is accurate, but the temperature will affect the data; For example, if you measure at 8 a
m
and 2 p
m
, the data will be different
After all, the indoor temperature is different
It's better to choose a time with high temperature
(4) Does the family need to close the window when measuring formaldehyde? Before the test, close all room doors and windows separately (the doors of each bedroom, kitchen and bathroom are closed separately) for 12 hours
If there is fresh air at home, the purifier will not open
If the doors and windows have been closed before, ventilate first and then close
(5) how long does it take to collect samples at home on site? It depends on the number of points you measured and the number of instruments we brought that day
