A leak checker that can be used for determining the sealing gas and for the glass parts of vacuum devices.
The "HF-20" is a high-frequency, high-voltage lamp checker that uses a Tesla coil. With transistor oscillation, the frequency is stable, allowing for reliable work. It is suitable for detecting leaks in light bulbs and electronic tubes, determining the presence of enclosed gases, as well as detecting leaks in glass ampoules and the glass parts of vacuum devices, and assessing enclosed gases. 【Features】 ■ Uses a Tesla coil ■ Frequency stability with transistor oscillation ■ Enables reliable work ■ Ideal for leak detection in light bulbs and electronic tubes *For more details, please refer to the PDF document or feel free to contact us.
