It is suitable for leak checks of quartz tubes, vials, and ampoules, as well as pinhole inspections of products lined on metal surfaces!
The "HF-20" is an inspection device used to detect the exhaust degree (vacuum level) of light bulbs and electronic tubes, as well as to determine the enclosed gas. It operates with a high voltage waveform in alternating current, and the output is adjustable in four steps. Additionally, it can be used as a pinhole inspection machine to check for pinhole defects in resin or rubber lined on metal surfaces. 【Features】 It is a high-frequency high-voltage lamp checker that uses a Tesla coil. By adopting a transistor oscillation method, the frequency is stabilized, allowing for reliable operation. 【Main Applications】 ◆ Leak detection or determination of enclosed gas in light bulbs and electronic tubes ◆ Leak detection or determination of enclosed gas in glass ampoules, quartz tubes, and the glass parts of vacuum devices ◆ Pinhole detection in films or thin sheets made of rubber, plastic, etc. ◆ Pinhole detection in resin or rubber lined on metal surfaces ◆ Pinhole inspection of enamel (porcelain) lined on metal surfaces *For more details, please contact us or download the PDF.
