N8320 is an analysis and diagnostic instrument specially developed by NGI for supercapacitor current leakage test. N8320 consists of three parts: test instrument, application software and test fixture. It can test the current leakage parameters of various types of supercapacitors under the set voltage. N8320 can be widely used in the R&D, production and quality inspection of supercapacitors, with the advantages of high cost performance, compact size and high accuracy. N8320 uses a standard 19-inch chassis with 2U height, which is convenient for integration into automation test platforms for R&D and production, and can also be used separately.
