Hypot Series - Dielectrical Widthstand Testers


The Hypot Series provides essential dielectric withstand (Hipot), insulation resistance, and ground continuity testing in a compact benchtop form. These testers are specifically engineered to help manufacturers and compliance labs verify insulation integrity and grounding connections for products like consumer electronics, appliances, and industrial controls. By supporting critical safety standards such as UL 1012 and IEC 60335-1, these instruments ensure routine production and pre-compliance testing are both accurate and efficient.

Built with safety and precision in mind, the series features SmartGFI® technology to protect operators from accidental electrical shock during high-voltage procedures. The hardware includes high-performance AC and DC sources, with the 3870 model offering comprehensive Insulation Resistance (IR) testing up to 1000V DC. Advanced arc detection and automatic shutdown on fault conditions provide an extra layer of protection, while the rugged construction ensures reliability in demanding production environments.

The series offers significant versatility through a range of models including the 3805 AC tester and the 3870 multi-function AC/DC/IR unit. Customization options such as PLC-ready outputs, 7 remote memories, and RS-232 interfaces allow for seamless integration into automated production lines. Users can further tailor the instruments with specialized options for 5 Ohm continuity or specific current output limits like 3mA or 5mA to meet unique testing requirements.
