2-in-1 Simultaneous Direct Particulate Readout and Gravimetric Sampling 

Have you ever had to co-locate devices in the field for direct dust reading and gravimetric sampling for compliance? If so, you know how inconvenient it is. Now, with the HAZ-DUST 7204, you can be alerted to problem areas and tasks, respond with controls to reduce exposures to hazardous particulate, confirm effectiveness of controls, and perform gravimetric sampling for compliance with ONE instrument simultaneously.  

Environmental Devices Corporation developed the highly effective and versatile personal HAZ-DUST 7204 specifically for industrial hygienists and other OEHS professionals. The HAZ-DUST 7204 comprises an accurate SKC flow compensated sampling pump and an optical sensor  sandwiched between a 25 or 37-mm filter cassette and interchangeable sampling inlet. The instrument reduces filter handling by allowing pre-loaded filter cassettes from certified laboratories. The sensor assembly clips directly in the worker’s OSHA-defined breathing zone for true particulate  exposure read-outs and sampling. Validated inlets are available for respirable and inhalable fractions, as well as thoracic.  

Aside from its versatility and accuracy, the HD 7204 is very easy and convenient to use, and workers like it too. The compact, lightweight HD 7204 features color touch screen operation, in-the-field calibration verification, an easy-to-clean optical sensor, 22+ hours run time, libraries for aerosol profiles and data set naming, optional networking, and so much more. The HAZ-DUST 7204 is the ideal particulate monitoring and compliance tool! 

A Solution for Each Size-selective Region of the Lungs

Easily switch between respirable and inhalable sampling heads (both meet ISO 7708/CEN criteria with validated performance) and the HAZ-DUST 7204 will automatically adjust flow rate for sharp size-selection and correction factors.
