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. Operate without an impactor for total dust measurement (NIOSH Method 0500) or target specific particle fractions by installing an inhalable, thoracic, or respirable impactor and selecting the appropriate calibration and flow rate. An in-line 37-mm cassette behind the sensor may be used to collect a concurrent filter sample for gravimetric or chemical analysis
HAZ-DUST IV with GS-3 Cyclone for real-time personal respirable silica monitoring
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 impactor
to the sensor, and use the selection switch on the monitor to apply the corresponding calibration and flow rate. Place a filter in the filter cassette behind the
sensor, zero the unit,
and clip the unit and sensor to a worker's clothing. Attach the
HAZ-DUST IV onto the worker's belt. Use the four-button keypad
to set the
threshold alarm and 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.
