Dust Monitor Calibration Laboratories

CIH Equipment’s laboratory employs a state- of-the-art dust generation chamber and a BGI aerosol generator for various makes and models of dust monitors. Technicians conduct a thorough cleaning and inspection to ensure clean optics, good-working mechanical factors and proper flow rate prior to calibration. The units are then subjected to an Arizona Road Dust test (ISO 21103-1, A1) and compared against a gravimetric filter, simultaneously subjected to the same test dust, and weighed.
