[China Instrument Network Instrument R&D] Formaldehyde is a colorless, water-soluble liquid that is highly volatile and has a pungent odor. It is mainly derived from building materials, furniture, artificial boards, various adhesive coatings, synthetic textiles, etc. Etc., especially when new homes are renovated, formaldehyde in the indoor air has become an “invisible killer†that endangers human health, so it is crucial for accurate detection of formaldehyde concentrations.
In 2017, all types of formaldehyde detectors on the market were already hot. There are hundreds of household formaldehyde detection products on the market. However, the detection of these formaldehyde detectors turned out to be surprising. The result of the comparison test of household formaldehyde detectors/boxes released by the Shenzhen Consumer Council in November 2017 shows that the 7 best-selling formaldehyde detection products on the market are all unreliable, with a maximum error of 228%. At the same time, the AQSIQ randomly organized 30 batches of samples of hand-held formaldehyde detectors that were completely annihilated and no one was qualified.
The development status of formaldehyde detectors on the market strongly promotes the emergence of truly accurate and efficient formaldehyde detectors. Recently, according to the Suzhou Hi-Tech Park of the Suzhou High-tech Zone, it was revealed that after more than six months of research, they have successfully developed a second-generation formaldehyde concentration detector. Their self-developed formaldehyde sensor chips and modules have made up for the deficiencies of other similar products on the market that have insufficient detection accuracy, can't be tested continuously, have a long warm-up time, have a slow and stable response, have a long calibration time, and have expensive imported instruments.
At the same time, the formaldehyde tester is only one-tenth the size of the original 'electronic clock' formaldehyde detector. It has completely independent property rights, has 15 patents, and has reached the international advanced level. It is the smallest formaldehyde detector in the country.
According to the relevant person in charge of the "National Branch Core Sense" of the Suzhou Institute of Industrial Science and Technology of the Chinese Academy of Sciences, the series of formaldehyde detectors will be listed in bulk after the Spring Festival, and the price will also drop from nearly 400 yuan for the original 'electronic clock' to 200 yuan. One. With the popularity of formaldehyde detectors, it is possible to strengthen the detection of the indoor environment and ensure the safety of people's lives. At the same time, it can also promote the development of the detection industry and the formulation of formaldehyde detector standards.
