Casella CEL-712 Microdust Pro Dust Monitor Rental $75.00 $225.00 $500.00

The CEL-712 Microdust Pro has the highest measurement range of any occupational dust measurement instrument available on the market. Up to 500 measurements can be taken and stored with the large memory. This data can be downloaded into Casella Insight Data Management Software, where it can be stored and analysed as necessary. Reports can easily be generated by location or person using the intuitive report wizard.

The CEL-712 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 CEL-712 Microdust Pro is incredibly easy to use with a simple interface. A user can be taking a measurement within seconds of starting the instrument. A calibration filter is used on site that provides a spot check of the instrument's linearity. This is unique to the marketplace as no other device currently has this capability. The screens are colour coded to ease navigation, once a measurement is started they turn green (shown below) 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.
