P-Trak Ultrafine Particle Counter 8525

SKU: 8525

The P-Trak Ultrafine Particle Counter Model 8525 measures workplace ultrafine particulate levels, as well as helping eliminate indoor air quality or IAQ problems.

Product Details

This portable instrument detects and counts ultrafine particles (smaller than 1 micrometer) 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. Unfortunately, the occupational health risks associated with manufacturing and using nanomaterials are not clearly understood. As a result, a need has arisen to assess workplace conditions. Using TSI’s proven technology, the P-Trak gives direct, real-time measurement of workplace ultrafine particulate levels.

The P-Trak Ultrafine Particle Counter locates obvious pollutant sources such as boilers, furnaces, and vehicles, and it also detects the not-so-obvious sources such as photocopy machines and printers. Use this instrument to detect the migration of toxic exhaust gases, malfunctioning office equipment, pinhole gasket leaks in boilers and a wide variety of other problems.
