A hipot tester (hi pot tester or hy-pot tester) is used to perform electrical safety tests on electrical components and products. The hipot test (along with dielectric withstand tests) ensures that the unit under test (UUT) meets operator safety requirements and meets the standards set forth by UL, CSA, IEC, and other standard certifying bodies. High grade hipot medical safety analyzers must be able to perform high precision hi-pot testing and have reporting capabilities to indicate tested equipment falls within required specification. Medical safety analyzers can notify if equipment falls into a defined specification.

The Guardian series hipot or dielelctric withstanding testers are advanced digital hipots with load and line regulation to ensure measurement integrity. Multi-step capabilities allow users to perform multiple tests in a sequence such as AC hipot followed by insulation resistance testing. The Sentry series is a compact, low-cost entry to hipot testing. Both series include Chroma's patented Open Short Check (OSC) feature, Flashover Detection, Ground Continuity Check, Ground Fault Interrupt (GFI), and Quick Discharge. Both meet UL Hipot Tester Requirements.
