The HAZ-DUST IV, with new infrared detector, displays immediate breathing zone measurements and comprehensive graph reporting
of aerosol and dust for industrial hygiene and environmental air investigations. Operate without an impactor for total dust measurement
(NIOSH 0500) or target specific particle fractions by installing an inhalable, thoracic, or respirable impactor. 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 and connect the appropriate impactor to the sensor. Place a filter in the filter cassette behind the sensor,
zero the unit, and clip the unit and sensor to a worker’s clothing. Use the four-button keypad to set the threshold alarm and begin monitoring.

• Real-time detection can also be used to determine and then
mitigate peak exposures, which will lower TWA levels as well.
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.
