Electrical Safety Testers

Hipot/Dielectric Analyzers

As a leading supplier of electrical safety test equipment, QuadTech offers a wide selection of nine instruments to meet a full range of testing needs. The new Sentry family of Hipot testers includes three low-cost, digital instruments for basic AC Hipot, DC Hipot and insulation resistance testing.

The Guardian Series gives you a choice among five instruments providing today's most popular combination of AC/DC voltage breakdown, ground bond and insulation resistance tests.

guardian A standard IEEE 488.2 interface, and optional RS232 port on the Guardian line, makes it easy to automate your electrical safety tests for employee safety and automatically archive test data. The Sentry and Guardian families feature a digital display and menu driven interface for ease-of-use, a compact foot print for reduced bench space and sensitive arc detection to minimize damage caused by unwanted voltage breakdown.

QuadTech testers have built-in test setup storage capabilities for easy recall. Safety features include a safety interlock to prevent accidents, a front panel test status indicator light and ability to lock out the operator from changing test set-ups.
