Pinhole tester for inspecting holes and scratches on the outer film of electrolytic capacitors.
The "Pinhole Tester" is a device that generates stable high DC voltage to conduct dielectric strength tests on the coatings of electrolytic capacitors. It can inspect for holes or scratches in the outer film of the electrolytic capacitor. The test is performed by applying voltage between an electrode that wraps around the outside of the tube and the case of the electrolytic capacitor. It can be turned ON/OFF remotely and comes with an acrylic cover to prevent accidental operation. 【Features】 ■ Generates stable high DC voltage for testing ■ Remote ON/OFF capability ■ Includes an acrylic cover to prevent accidental operation *For more details, please refer to the PDF document or feel free to contact us.
