The HAZ-DUST 7204 is an instrument for concurrent dust monitoring and gravimetric dust sampling. Its large colour touch screen shows a real time graphical display of airborne particulate concentration in the breathing zone. By combining a flow compensated pump for gravimetric sampling with an optical sensor for particulate monitoring the HAZ-DUST 7204 removes the need for two separate devices.
- Easy touch screen operation
- 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 inlets for Inhalable, Thoracic and Respirable measurement
- Can accept pre-weighed and preloaded 25 or 37 mm filter cassettes
- Small and lightweight with integral belt clip
- Operates for over 22 hours using rechargeable Li-Ion battery
- Automatic data logging
- Multiple language options
- Easy to use DustComm Pro Software for data downloading, trend analysis and comprehensive reporting of concentration changes over time

The HAZ-DUST 7204 optical particulate sensor 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.
