CBS (Chamfered Barnacle Professional scraper) probes are Zetec's most popular solution for basic tubing inspections. As the name implies, these probes are designed to push through and 'scrape' away residue to make sure that the entire length of each tube can be inspected. These probes are available in both the standard economical version as well as a heavy duty 'long-life' version. Intended primarily for inspection of straight sections of non-ferromagnetic tubing, these probes are typically offered in diameters of 10mm (.400") to 25mm.
