Hipot & Safety Testers

AC/DC Hipot testers, Ground Bond, Insulation Resistance, Leakage Current

Hipot testers or dielectric withstand testing instruments are used for conducting electrical safety tests on electrical components and products to make certain they are in compliance with IEC, UL, TUV, CSA, EN, and other electrical safety requirements. In addition to general product and component testing, Chroma can help solve complex medical safety testing (60601-1) ensuring human safety and product reliability. New hipot and electronic safety test instruments (EST) purchased in North America are backed by a 2-year standard warranty.

Hipot Testers

Hipot testers determine the suitability of the dielectric or insulation barrier between hazardous and non-hazardous parts. Hipot testing (dielectric strength testing) appears in nearly every product safety standard and is a fundamental test used to check a fully assembled product as it exits the production line.
