The SCI 2955 is a popular type of Hipot tester. These instruments are designed to simplify every aspect of safety testing for operators of all comfort levels. Our 2900 Series includes the most intuitive user interface in the industry and won’t take up too much space on the production line. With multiple memories and an optional RS-232 interface, you can quickly perform tests on a variety of DUT’s from the front panel or with a PC. Use this series in stand-alone applications or interconnect with a 2600 series tester to form a complete test system for NRTL compliance.
