The TSI 8525 P-Trak Ultrafine Particle Counter (UPC) is an ideal instrument measuring workplace ultrafine particulate levels as well as helping eliminate indoor air quality (IAQ) problems. This portable instrument detects and counts ultrafine particles that often accompany or signal the presence of a pollutant that is the root cause of complaints.
Ultrafine particles are defined as having a diameter less than 0.1 μm (or 100 nm). Engineered nanoparticles (nanomaterials) are a subset of ultrafine particles with dimensions from 1 to 100 nm. Nanomaterials are produced and used for industrial and high-tech applications, while ultrafine particles are the byproducts of combustion and other chemical reactions.
