Formaldehyde can not be ignored. Formaldehyde detectors and other instruments help to ensure the safety of people's housing

formaldehyde is a highly toxic substance, ranking second on the priority control list of toxic chemicals in China. Formaldehyde has been identified by the World Health Organization as a carcinogen and teratogenic substance. It is recognized as a source of abnormal reactions and one of the latent strong mutagens. Formaldehyde poisoning will cause great harm to human body

recently, the problem of formaldehyde exceeding the standard has become a heated topic in the country, and the long-term rental brand has also been pushed to the forefront. Houses are places where people live and rest. Air quality and safety is very important, but it is often difficult to be guaranteed after colliding with capital, especially after encountering some unscrupulous businesses

formaldehyde, a colorless gas, has a special irritating smell and has irritating effects on human eyes, nose, etc. When formaldehyde reaches a certain concentration indoors, people will have discomfort, which will cause acute poisoning, manifested as burning pain in the throat, dyspnea, pulmonary edema, liver transaminase rise and other symptoms. Long term exposure to formaldehyde will increase the risk of human suffering from Hodgkin's lymphoma, multiple myeloma, myeloid leukemia and other special cancers. It can be said that formaldehyde is recognized as the number one indoor killer. On October 27, 2017, the international agency for research on cancer of the World Health Organization classified formaldehyde as a carcinogen

recently, Alibaba employees who died of leukemia because of formaldehyde in the free rental house have been searched. Although the cause of death has not been clearly determined, after testing, the formaldehyde in the rent where the employees live seriously exceeds the standard, not to mention having lived for two months, which is unlikely to be harmful to human body

at present, China is promoting the construction of the blue sky defense war, so that people can breathe healthy air outdoors, but the indoor environment, as the place where people live and work for the longest time, has not been paid attention to. Especially at present, there are more and more people renting houses in our industry, and the harm caused by formaldehyde problem can not be ignored

as a tenant in the city, the body is the capital of revolution. After the problem of formaldehyde exceeding the standard appears, how can we know whether the formaldehyde in the house we live in exceeds the standard? At present, the common detection methods in the market mainly include AHMT spectrophotometry, gas chromatography, electrochemical sensor, formaldehyde self-test box, etc

among them, high performance liquid chromatography (HPLC), gas chromatography (dnph-gc) and spectrophotometry are the most accurate and professional formaldehyde detection methods. In addition to the obvious relaxation characteristics of these high-precision instruments, formaldehyde detectors and formaldehyde detection boxes are also popular in the market. Hand held formaldehyde detectors are generally convenient, but fluctuations in temperature and other factors can easily affect the detection results. Formaldehyde detection box is a kind of test tool that can detect the content of formaldehyde. The jjg139-1999 verification regulation requires that the allowable error of its indication value is usually no more than ± 1%. It is used for consumption and may cause serious consequences. People who may have a rapid semi quantitative experience of formaldehyde in the living environment can judge the degree of formaldehyde pollution

but at present, in the market, most formaldehyde detection instruments are not reliable after being tested by many testing institutions. Many household formaldehyde detectors are just a simple piece of electronic components. They not only use poor sensor components, but also put them on the market without system calibration and testing. The measured results are basically inaccurate, and the values vary greatly

therefore, in addition to the use of specific instruments, tenants can entrust professional formaldehyde testing companies to use professional testing instruments for indoor testing. At present, there are many testing companies in the market, such as third-party companies with national CMA qualification. Their testing data are authoritative and can be used as a legal basis. The testing report is stamped with the seal of CMA. The testing items generally include formaldehyde, benzene and TVOC

formaldehyde, as a carcinogenic gas, we must pay more attention to it in our daily life. I believe that with the explosion of formaldehyde time, the detection of formaldehyde gas will become more standardized in the future, and there will be more room for the development of formaldehyde detection instruments
