metallized film tester

The utility model relates to a metalized film tester which is composed of a high voltage generator, an electric voltage sample circuit, an electric voltage display circuit, an overcurrent protection circuit, a testing electrode and a workbench. A fixed electrode is a current conducting plate which has a certain surface area, the workbench is also provided with a sheet resistance testing device and a surface texture viewing device, and one end of the workbench is connected with a film roll supporting frame. By adopting the large-area current conducting plate as an electric pole, the measured voltage resisting values can factually reflect the actual voltage resisting condition of the film, and the sheet resistance testing device, a surface texture checking device and an electrostatic absorption checking device are all arranged on the workbench. Thus, the utility model has the advantage of little space occupying and is convenient for tests and management.
