The new P-Trak™ Ultrafine Particle Counter (UPC) is designed to detect and track ultrafine particles (smaller than 0.1 micrometer dia) that often accompany or signal the presence of a pollutant that is the root cause of IAQ complaints, says the company. It can be used to identify the migration of toxic exhaust gases, malfunctioning office equipment, pinhole gasket leaks in a boiler, and a wide variety of other problems, says the company. Battery-operated, it goes wherever needed. With data logging and field-proven software, measurements can be made in the field and data can be taken back to the office for further study, says the company.
