151147A IS Microdust 880 Data Logging with Ranges 0 - 25 & 0 - 250 mg/m3 by Casella

The Microdust 880 IS is a true real time dust and particulate monitor that allows the user to accurately and quickly measure the level of concentrations of particles in the air. An optical system is used based on a forward light scattering method and this ensures excellent linearity across a wide range of concentrations and particle sizes. Average, current and maximum levels are calculated and displayed on a clear dot matrix display and the unit features a built in data logger to store the results of up to 30,000 readings. A wide range of useful accessories is readily available to enhance the benefits of this intrinsically safe instrument in any workplace area.

Key benefits

  • UL and ATEX approved for use in hazardous areas
  • Measurement of particle sizes from 0.1 to 12 microns
  • Measurement ranges from 0.1 up to 25,000 depending on application
  • Data logger with up to 30,000 point capacity
  • Field calibration with standard optical insert filter
  • Purging bellows provided for setting instrument zero
  • Rechargeable battery pack
  • Range of adaptors for size specific sampling or respirable sampling
  • 2 line 16 character display
  • 4 large keys for easy operation even with gloves
  • Weight only 16 oz with probe

Applications

  • Walk through surveys
  • Workplace monitoring
  • LEV filter efficiency
  • Ambient air quality
  • Indoor air quality
  • OSHA or NIOSH surveys
  • Process monitoring
  • Dust emission checks
  • Boundary emission checks

An 880 nm wavelength infrared light beam is used in the optical probe of the Microdust 880 IS. The system is calibrated in a wind tunnel against a known gravimetric sample and a calibration insert filter is produced. The user can bring the instrument back to its original factory calibration condition at any time using the calibration filter.

Dust particles in the sampled air cause the light beam to be scattered thereby producing a known electrical response that produces an extremely linear output signal across the range of sizes of interest. Each instrument is provided with a high and a low measurement range for ultimate flexibility in measurement possibilities.

The size selective adaptor can be fitted over the probe and various PUF filters used to limit the size sensitivity of the system to look for PM10, PM2.5 or the respirable fraction of the dust. An enclosure is available for fixed site monitoring that incorporates a sampling pump and rechargeable battery pack to give up to 24 hours field operation.
