The Sentry Plus instruments provide a complete dielectric testing solution.
The Sentry 10 Plus for AC Hipot testing, the Sentry 20 Plus for AC/DC Hipot testing and the Sentry 30 Plus for AC/DC Hipot tests plus IR measurements.
The large enhanced digital display and user friendly controls of the Sentry Plus instrument allow test parameters and limits to be easily programmed and viewed.

The Sentry 10 Plus AC Hipot Tester performs AC dielectric withstand (hipot) tests.
The test voltage is programmable from 50V to 5kV AC with a resolution of 1V.
The current range is 1µA to 20mA.

The Sentry 20 Plus AC/DC Hipot Tester has all the features of the Sentry 10 Plus in addition to DC hipot capability.
The test voltage is programmable from 50V to 6kV DC with a resolution of 1V.
The current range is 0.1µA to 5mA.
