Do you really choose the right method for indoor formaldehyde concentration detection?

Update Date: 20:54, November 24, 2018 Views: 120
We all know that long-term exposure to low-dose formaldehyde will cause chronic respiratory diseases, young people's memory and intelligence decline, fetal malformation and cancer and other diseases! However, what's more frightening is that more and more families are decorating new houses, and their families are living in the environment where formaldehyde exceeds the standard every day, but they don't realize it. For the sake of everyone's health, Xiaobian thinks it is necessary to detect the indoor air pollutants.
 
1、 Sensory method
 
Because formaldehyde is a kind of gas with strong pungent smell. If you can smell a pungent smell in your house, it means that the formaldehyde content in the house exceeds the standard and the air pollution is serious. Therefore, it is necessary to remove the formaldehyde gas in the room immediately, Although this test method is direct, if the formaldehyde concentration is too high to be heard, it means that people living indoors have been injured by formaldehyde for a long time, and it is inevitable that they will be ill. This method can not be used when the concentration of formaldehyde is less than a certain degree, and the cost is too high.

2、 Formaldehyde detection box method
 
Buy the formaldehyde detection box on the market, and seal the space where the formaldehyde content is to be detected. After one hour, operate the formaldehyde detection box according to the instruction manual, put it into the sealed space, and after standing for dozens of minutes, compare the color of the formaldehyde detection box with the color card, and estimate the concentration value of formaldehyde content in the detection space, This is a more economical and practical test method, but it tests your color discrimination ability. The test box purchased from a certain treasure is used in the test. After the test, it is completely impossible to determine whether it is 0.02 or 0.06. The test results of different sellers' test boxes are completely different. Combined with the working principle of the detection box, the accuracy of the detection box is very low, and it can only be used as a test box Rough reference.

Third, professional formaldehyde company detection
 
At present, the instruments used by formaldehyde companies to detect formaldehyde are generally very accurate. The detection instruments generally use spectrophotometer. The values detected are relatively accurate, but the detection cost is higher than the first two. Formaldehyde in more than 2-3 times is when there is no smell, generally can not smell, so Xiaobian suggested to choose a professional indoor formaldehyde company for testing, if the detection exceeds the standard, it can also be treated immediately. Generally, the doors and windows should be sealed for 12 hours before testing.
