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 from the menus the desired particle type, connect the appropriate sampling head to the sensor, and place a filter in the filter cassette behind the sensor if collecting a concurrent filter sample. Zero the unit and then 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 Haz-Mat air quality investigations and monitoring waste site remediation
• All air monitoring applications involving lung damaging particulates
