Description

(1) Technical field

[0001] The invention relates to a vacuum tube measuring device, in particular to a pocket high-voltage vacuum tube tester for testing the quality of the vacuum tube by utilizing the high-voltage electric breakdown characteristic. (2) Background technology

[0002] At present, to detect the quality of the vacuum tube, only when the vacuum tube is produced, the vacuum pump is used to pump air, and the vacuum degree of the vacuum tube is measured with an air pressure vacuum degree measuring instrument. For the vacuum tube that has been formed, it is impossible to measure the vacuum degree in the airtight container except for the complicated leak detection method. There is no report about an instrument that can detect the quality of formed vacuum tube products. In terms of mining electromechanical products, users of vacuum tubes do not have equipment to measure the quality of vacuum tubes, so they cannot regularly test the quality of vacuum tubes. Only when...
