The TQC Low Voltage Pinhole detector from Gardco enables users to inspect various coatings on conductive substrates for small defects such as holidays and pinholes using the "wet sponge technique."
The earliest versions of atom probes only had a pinhole detector, unlike our wide-angled position detector, and so gave an image like a geological borehole in a single dimension.'
has introduced the Model PDC-20 In-Line Pinhole Detector. The nondestructive system is said to be an economical alternative to expensive in-line optics or visual inspections, which can yield high levels of scrap.
Buckleys has launched a new Low Voltage Pinhole Detector, the LVPD.
The Buckleys PHD Pinhole Detector can detect slight nicks and breaks in insulation--difficult to detect by visual inspection, yet sufficient to give a patient a serious burn or a surgeon a distracting shock.

Low-voltage pinhole detectors are commonly used to inspect coatings thinner than 500 [micro]m applied to concrete and other conductive substrates.

Binks' pinhole detectors are built to work with flat materials, but can work with formed products in some cases.
The SHD-4000 is said to be useful in applications where more sophisticated pinhole detectors are cost prohibitive but where product defects of 1 mm or larger cause serious problems.
