DustComm Pro Software for downloading, basic trend analysis, and
comprehensive graphical reporting
Easy operation
  |
The HAZ-DUST IV personal real-time aerosol monitor, with new infrared detector, provides you with immediate breathing zone measurements of aerosol and dust for industrial hygiene and environmental air investigations. The small, lightweight unit attaches onto a worker's belt while the miniature sensor easily clips to a worker's collar. Select from inhalable, thoracic, or respirable sampling heads to target a specific fraction. An in-line 37-mm cassette behind the sensor allows the user to collect a concurrent filter sample for gravimetric or chemical analysis. A user-adjustable alarm may be set to alert the user to approaching threshold limits. When monitoring is completed, use the included DustComm Pro Software on a PC to download data from the HAZ-DUST IV and produce management-ready graphs and reports |
Easy-to-use HAZ-DUST IV
Four simple keys and menu-driven instructions displayed on an easy-to-read
LCD make HAZ-DUST IV operation easy. Simply select
the desired particle type and connect the appropriate sampling
head to the sensor. Place a filter in the filter cassette behind
the sensor if collecting a concurrent filter sample. Zero the unit
and clip the sensor to a worker’s collar. Attach the
HAZ-DUST IV onto the worker’s belt. Use the four-button keypad
to begin monitoring.

Principle of Operation
HAZ-DUST IV operates on the principle of near-forward light
scattering of infrared radiation. It immediately and continuously
measures the concentration of airborne dust particles and displays the
result in mg/m3.
What is near-forward light scattering? This measurement technique
uses an infrared light source positioned at a 90-degree angle from a photodetector.
As the airborne particles enter the infrared beam, they scatter the
light. The amount of light received by the photodetector is directly
proportional to the aerosol concentration. Unique signal processing
internally compensates for noise and drift.
Applications
- Determining levels of worker respirator protection for OSHA compliance
- Reviewing compliance programs
- Evaluating work practices and controls of any dust-generating practice
- Performing safety audits
- Combine with NIOSH video exposure monitor for real-time graphical overlays
- Monitoring welding fume exposures
- Performing air quality studies in occupational health and industrial hygiene
- Performing hazmat air quality investigations and monitoring waste site remediation
- All air monitoring applications involving lung damaging particulates
