Sampling System Determines Inhalable Dust Content

Jan. 21, 2019
To measure workplace dust and particulate, new instrument measures inhalable dust content and the respirable fraction that may reach the lungs.

The new VC25 JI stationary tester developed by JUNG INSTRUMENTS measures particulate matter and total dust content in the workplace. A high-precision flow-rate sensor, manufactured exclusively for this system, complies with all commonly applied standards developed by the IFA, the German Institute for Work Safety.

Dust pollution legislation requires that dust-content measurement be carried out directly proximate to workers or at the emission source. The VC 25 JI dust collection system is a stationary sampling unit designed to measure dust loads in workplaces, in a wide range of industries. The system measures the inhalable dust content (specified in IFA standard 7284) and the respirable fraction that may reach the lungs (specified in IFA standard 6068) according to EN 481, using sampling heads for dust and particulate matter licensed by the IFA.

The core elements of the new instrument are the high-precision flow-rate meter, manufactured exclusively for Jung Instruments, and the new, user-friendly electronics. The electronic system is designed to keep the flow rate at exactly 22.5 m3/h at all times, independent of any ambient temperature or flow-resistance variations. The instrument comes with software for self-diagnosis to monitor the filter condition. Fault messages, e.g., about an obstructed or defective filter, are indicated on the LCD.

The instrument combines new technology for controlling the flow rate and for facilitating handling with tried-and-tested methods for dust measurement.

“Many companies use dust-sampling systems that already have reached their economic end-of-life, but not so the measuring heads that work with the samplers. The new VC 25 JI is the solution many operators have been waiting for: They can now continue using the existing measuring heads,“ explained Jung Instruments founder and managing director Erwin Jung.

The cartridges accommodating the flat filters are easy to handle and can be taken or shipped to a laboratory for subsequent gravimetric and chemical analyses.
