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. 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. Attach the HAZ-DUST IV onto the worker's belt. Use the four-button keypad to set the threshold alarm and begin monitoring.
