The PID total volatile gas detector is a portable handheld upgraded versionEST-10-Ⅱ-TVOCThe gas concentration measuring instrument is a natural diffusion gas detection method, which can be equipped with a gas sampling pump for measurement. At the same time, it has added data storage function and can be connected to a computer to export data.
The main sources of TVOC are outdoors, mainly from fuel combustion and transportation; while indoors, they mainly come from combustion products such as coal and natural gas, smoke from smoking, heating, and cooking, adhesives, coatings, paints, boards, wallpapers, furniture, household appliances, furniture, and human body emissions. There are nearly a thousand types.
In the process of interior decoration, TVOC mainly comes from paint, coatings, and adhesives. According to reports, the indoor TVOC concentration is usually between 0.2mg/m ³ and 2mg/m ³, and in improper decoration construction, it can even be tens of times higher. Indoor various aromatic hydrocarbons and alkanes mainly come from automobile exhaust (76% -92%). The TVOC content in general paint is between 0.4-1.0mg/m ³.
Main contents: hydrocarbons, halogenated hydrocarbons, oxygenated hydrocarbons, and nitrogen-containing hydrocarbons, including benzene derivatives, organic chlorides, Freon series, organic ketones, amines, alcohols, ethers, esters, acids, and petroleum hydrocarbon compounds.
