Sampling Probe SYS 529

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.

Standards

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.

Benefits

• location-independent count rate
• precise scanning even in filter corners
• low scanning time due to larger probe width (transverse to the scan direction)

Applications

• leakage testing of built-in filter systems

Accessories

• cap
• antistatic silicone hose (diameter 7.9 mm)
