The MICRODUST pro from Casella is a portable, real time monitor for assessing the concentration of suspended particulate matter. It is probably the most versatile instrument available with the ability to measure from 1ugm-3 to 2500 mgm-3. It is the only hand-held real-time dust monitor on the market capable of graphically presenting variations in dust concentration on a real time scrolling graph - no longer is it necessary to wait to analyze results on a PC.
The MICRODUST pro measures particulate concentrations using a near forward angle light scattering technique. Infrared light of 880nm wavelength is projected through the sensing volume where contact with particles causes the light to scatter. The amount of scatter is proportional to the mass concentration and is measured by the photo detector. By using a narrow angle of scatter (12-20o) the majority of scattered light is in the diffracted and refracted components, which minimizes the uncertainty associated with particle color, shape and refraction index.
The MICRODUST pro has the advantage that there is only one model which covers the entire measurement range (0-2500mgm-3). It is possible to "fix" the range of the instrument, or have it as an "auto-ranging" device.
Each MICRODUST pro is individually factory calibrated, using a gravimetric technique. This instrument can be returned to its "factory" calibration setting at any time during its life by the use of a non-degradable calibration insert. An individual gravimetric calibration is also possible.
