Rectangular Sampling Probe SYS 528 for leakage and integrity testing according ISO 14644-3 for a sample flow rate of 50 l/min

Isokinetic sampling probes are required, for example, for leakage testing of built-in filter systems in cleanrooms and cleanroom facilities. In the existing standards and guidelines, probes with rectangular cross-sections are recommended.

The Topas probes have a rectangular cross-section at the suction point, which merges steadily into a round cross-section for the hose connection. The manufacturing process guarantees a high-quality, smooth surface inside the probe, including all transitions. The constructive design of the probe is based on the international standard ISO 14644-3 as well as the VDI guideline 2083-3. The probe geometry depends on the volume flow of the particle counter used and the required probe inlet velocity.
