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.
It is recommended that in most applications, dust monitor calibration is done on an annual basis is suitable and sufficient, however, there may be instances where more frequent or multiple calibration exercises are required, such as due to periodic process changes. CIH will advise on the most suitable regime that is required.
All instrumentation is calibrated to our ISO 17025 accredited facility. Our trained technicians take a very thorough and detailed approach to servicing and calibrating your dust monitors. We're as concerned for worker safety as you are. A functional test is the initial step in diagnosing the current condition of your dust monitor.
