An instrument or device that collects atmospheric pollutants or contaminated atmosphere. There are many types of atmospheric samplers. According to the collection object, it can be divided into gas (including vapor) sampler and particle sampler; it can be divided into environmental sampler, indoor sampler (such as sampler used in factory workshop) and pollution source sampler (such as chimney) according to the place of use. Sampler). In addition, special-purpose atmospheric samplers, such as samplers that collect gas and particulate matter at the same time, can collect sulfur dioxide and particulate matter in the atmosphere, or hydrogen fluoride and particulate matter, to facilitate the study of the relationship between sulfur and fluorine in gaseous and solid materials. There is also a sampler that collects bacteria from the air. The atmospheric sampler is an instrument or device that collects atmospheric or contaminated air. There are many types, according to the collection object can be divided into gas sampler and particle sampler; according to the use of the site can be divided into environmental sampler, indoor sampler and pollution source sampler. In addition, there are special-purpose atmospheric samplers, such as samplers that collect both gas and particulate matter. The gas sampler generally consists of a collector, a flow meter and an aspirating power system. Atmospheric samplers work well for the detection of air and harmful gases in the environment. With the continuous advancement of science and technology, atmospheric samplers are constantly introducing new products, such as intelligent atmospheric samplers, explosion-proof atmospheric samplers, dual-gas atmospheric samplers, etc., which greatly enrich the classification of atmospheric samplers. With the increasing attention to environmental issues in the country, there are more and more companies that produce environmentally friendly instruments such as atmospheric samplers. Thanks to the continuous research and development of research teams led by these entrepreneurs, today's atmospheric samplers are more accurate and more complete. Such as: Tianrui Instruments, Xinbao Technology. The atmospheric sampler is only a part of the sampling instrument, as well as individual samplers, dust samplers, dust samplers, explosion-proof samplers, and so on. Features: 1, small size, easy to use, easy to carry 2. The first domestically produced volumetric vane pump made of imported DC brushless motor is used as sampling power. The pumping vacuum is high, the flow is stable, and the fault-free running time is long. 3. This product adopts CPU control, simple to use and reliable in performance. 4. The instrument is dual-purpose AC and DC, and has a low-temperature sampling function. It works in a low-temperature environment by the automatic constant temperature heater controller to heat the sampler circuit to ensure that it works at constant temperature.
