HAZ-DUST IV, Personal Monitor, 110-240 V, Logging Overview

HAZ-DUST IV (datalogging) Personal Dust Monitor with detachable sensor with thoracic impactor, in-line filter cassette, NiMH battery, 110-240 V charger, HAZ-DUST Media CD with manual and DustComm Pro software, computer interface cable, and carry case
Measures 0.01 to 200 mg/m3
EDC No. HD-1004

The HAZ-DUST IV personal particulate monitor displays immediate breathing zone measurements, including TWA, STEL, Max, and Min without an impactor or sample pump. Interchangeable impactors for inhalable, thoracic, and respirable particulate are available. Use the HAZ-DUST IV for industrial hygiene and environmental air investigations.

Worker wearing HazDust sampling train
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

    • The only real-time personal dust monitor with both a sensor and a cyclone/filter cassette in the breathing zone

 

    • Concentrations over user-defined target levels can be further characterized and quantified by laboratory analysis of the filter

 

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

 

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.
