The CEL-712 Microdust Pro Particulate Monitor is a rugged, hand held, data logging instrument for real-time detection of airborne dusts, fumes and aerosols. The Microdust Pro can be used for spot checks and walk through surveys with the advantage of seeing instantly when and where excessive dust levels are occurring. The Microdust Pro is incredibly easy to use with a simple interface. A user can be taking a measurement within seconds of starting the instrument.

An optical insert is used on site that provides a spot check of the instrument’s calibration response. The screens are color coded to ease navigation, once a measurement is started they turn green or red when stopped. When taking a measurement, real time instantaneous and average levels are shown and subsequently stored to the memory for review later.

The instrument is factory calibrated using a method traceable back to isokinetic techniques and is conducted in a custom-built wind tunnel using ISO 12103-1 A2 Fine test dust (Arizona road dust equivalent). Each probe is also supplied with it own unique Calibration Insert, which creates a known optical scattering effect in the probe’s sampling chamber. This fixed reference can be used to confirm the original factory calibration point, although annual factory recalibration is recommended. While the Microdust Pro comes factory calibrated, by using an optional Apex2 Air Sampling Pump and gravimetric adaptor user defined dust type settings may be obtained. This means that the user can calculate a correction factor for the actual type of dust being measured and ensures maximum accuracy for their particular application.

The Microdust Pro Particulate Monitor can be downloaded to Casella Insight Data Management Software using the USB cable provided. Once downloaded, the time history of the dust level can be displayed and analyzed as necessary, so the times and extent of particularly “dusty” events can be seen. Measurements can be stored in relation to the person or area they were measured and reports can be produced showing the relevant data for multiple people or places as required.
