Dust Monitor Calibration at CIH Equipment:
Our A2LA ISO 17025 accredited dust calibration lab is based on comparison with a gravimetric standard, the gold standard for dust calibrations. We use a negatively pressurized chamber and a constant feed dust generator and ISO test (ISO 21103-1) particle size distribution dust (Arizona Road Dust).
Our trained technicians take a very thorough and detailed approach to servicing and calibrating your dust monitors. Technicians first conduct a thorough inspection to ensure proper flow rate and that mechanical factors are in good working condition. The device’s optics, filters and inlet ensembles are cleaned before/after calibration. If required, filters are also changed at this time. After calibration is complete, all components will be cleaned again.
It recommended that in most applications, dust monitor calibration is done on an annual basis, however, there may be instances where more frequent or multiple calibration exercises are required, such as due to periodic process changes.
