Rotating Probes (PR) : ETherNDE

Rotating Probes (Reflection) are available in two options, Rigid Stainless Steel and Delrin Flexible.

Rigid stainless steel probes offer high wear resistance, where as the flexible probes are used where hole tolerances are poor and access is not directly in-line with the hole.
