Pinhole detector

Pinhole detector

It detects pinholes with an easy-to-hold probe.

We handle the "Pin Hole Detector," which is used to inspect pinholes in coatings and linings (paint films, resins, rubber, and other insulators) on various metals. By applying high-frequency high voltage, pinholes can be confirmed under discharge conditions. It can be used for full circumference inspections of both the inner and outer surfaces of containers. Please feel free to contact us if you have any requests. 【Features】 ■ Pinholes can be visually detected by the sparks from high-voltage discharge. ■ By replacing the tip electrode, it can be used for inspection of various shapes regardless of the product shape inside the container. ■ Operation is simple. When the power switch and high-voltage discharge switch are turned ON, discharge begins from the probe, etc. *For more details, please download the PDF or feel free to contact us.
