TSI Ultra fine Particle Counter 8525 Product Overview:
The TSI8525 ultrafine particle counter can detect particles with a diameter less than 0.1 microns and count them It is generally believed that these particles are often accompanied by the presence of pollutants, so the pollution source can be identified through the detection of ultrafine particle counters. Both obvious pollution sources (such as boilers and motor vehicles) and non obvious pollution sources (such as photocopiers and printers) are difficult to deceive in front of the ultrafine particle counter, and non obvious pollution sources (such as photocopiers and printers) are difficult to deceive in front of the TSI8525 ultrafine particle counter in the United States. It can successfully identify the migration of toxic gases, office facilities with pollution problems, production workshops, boiler gasket leaks, and many other issues.
The problem of IAQ caused by ultrafine particles
Ultra fine particles refer to particles less than 0.1. The proportion of ultrafine particles (UFPs) in a certain amount of air is high, but their mass concentration is only a small fraction. More and more studies have shown a very close relationship between ultrafine particles (UFPs) and health. In thousands of building air quality (IAQ) surveys, air quality issues are related to ultrafine particles (UFPs).
The mass of 10 million 10nm particles is only the same as that of 1 μ m particles
Ultra fine particles (UFPs) are typically products of combustion and chemical reactions. These particles may be generated indoors or outdoors, with sources including motor vehicle emissions, production processes, smoking, cleaning agents, office equipment, etc.
Ultra fine particles (UFPs) will migrate or flow from high pressure to low pressure areas with the flow of air. P-Trak can quickly locate pollution sources.
