HAZ-DUST IV Particulate Monitor

The HAZ-DUST IV displays immediate breathing zone measurements and comprehensive graph reporting of aerosol and dust for occupational hygiene and environmental air investigations. Interchangeable sampling heads enable specific particle fractions to be targeted. An inline 37 mm cassette, located behind the sensor, may be used to collect a concurrent filter sample for gravimetric or chemical analysis.

Easy operation and instantaneous, continuous display of TWA, STEL, Minimum, Maximum concentration in mg/m³
Sensor mounts directly in the breathing zone for a personal sample
Interchangeable sampling heads for Inhalable, Thoracic and Respirable measurements
External switch to select between respirable calibration to NIOSH 0600 and 2.75 L/min flow rate (GS-3 Cyclone) or inhalable calibration to NIOSH 0500 and 2 L/min flow rate (IOM Sampler)
In-line 37 mm cassette (or optional 25 mm cassette using adaptor) for collecting a concurrent filter sample for gravimetric or chemical analysis
Small and lightweight with integral belt clip
Operates for over 8 hours using rechargeable NiMH battery
Automatic data logging
Easy to use DustComm Pro Software for data downloading, trend analysis and comprehensive reporting of concentration changes over time

Specifications

HAZ-DUST IV operates on the principle of near-forward light scattering of infrared radiation. 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. It immediately and continuously measures the concentration of airborne dust particles and displays the result in mg/m³.
