Formaldehyde treatment needs to be tested before it can be admitted to a new house. Otherwise, it may have an impact on human health. Generally, formaldehyde treatment undergoes five detection methods:
1. Formaldehyde test paper: It is very cheap, but if a certain amount of formaldehyde in the air is not collected, it is impossible to calculate the mg/m unit of formaldehyde content. In addition, through visual reading, the value error is too large.
2. Formaldehyde detector detection: photoelectric photometric method is generally used to detect test paper. Each time/point/room test, test papers need to be replaced.
3. Formaldehyde Detection Norformaldehyde Company: We need to know about the formaldehyde company. First, we need fairness. Second, we need professionalism.
4. 仅用于甲醛检测的第三方小型检测机构:这些机构一般由高校实验室、小型检测公司和社会半公益性检测机构组成。由于只检测不做治理，检测结果是公正的，检测设备相对好一些，知识也较强。价格检测房一般以100 200元预约，比较符合一般家庭的需要。
4. Small third-party testing institutions for formaldehyde detection only: these institutions are generally composed of University laboratories, small testing companies and social semi-public welfare testing institutions. Because only testing does not do governance, the test results are fair, testing equipment is relatively better, and professional knowledge is strong. Price testing rooms are generally booked at 100,200 yuan, which is more in line with the needs of ordinary families.
5. Third-party testing company with CMA testing qualification: The testing company approved by the Government Metrology Bureau and awarded CMA testing qualification is very impartial and professional. The inspection report issued by the company with CMA Chapter has legal effect and can be directly used in litigation. Of course, in kindergartens, schools, hospitals, business disputes and other occasions, extremely responsible parents and Tuhao families can also choose.
