SENTRY 30 QuadTech HiPot

The SENTRY 30 is a Hipot from QuadTech. Hipot, or high potential, is a class of electronic test equipment used to verify electrical insulation. Engineers use hipot-testing instruments on cables, wires, circuit boards, appliances, electric motors, and transformers. As a product ages, its insulation may break down and result in current flow leakage. Hipot testers keep engineers safe from current leakages by detecting gaps and defects in the electronic device.

The QuadTech Sentry 30 combines both AC and DC Hipot with insulation resistance (IR) measurements into a single compact unit. The front panel of the Sentry makes it easy to operate. Digital display and user-friendly control allows test parameters and limits to be set easily without the high voltage activated.

The Sentry Series of electrical safety testers are advanced digital hipots with load and line regulation to ensure measurement integrity. Multistep capability allows the user to perform up to two tests in a sequence such as AC hipot followed by IR.

The Sentry 30 AC/DC/IR Hipot Tester has all of the features of the Sentry 10/15 and 20/25 plus measurement of insulation resistance. The IR measurement range is from 10MW to 10GW with test voltages from 50 to 1000V DC.
