The HAZ-DUST, with new infrared detector, displays immediate breathing zone measurements and comprehensive graph reporting of aerosol and dust for industrial hygiene and environmental air investigations. Target specific particle fractions by installing an inhalable, thoracic, or respirable sampling head. An in-line 37-mm cassette behind the sensor may be used to collect a concurrent filter sample for gravimetric or chemical analysis. |
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 set the
threshold alarm and begin monitoring.

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.
