    Digital Display—Digital displays show a numeric reading on an LCD.
    Analog Display—Analog displays show the magnitude and rate of change so you can see rapidly changing resistance values more easily than on a digital display.
    Light-Indicator Display—Light indicator displays have a scale with LEDs that light up to show the resistance as good, caution, or bad.

    Hand Crank-Operated Insulation Testers

    Turn the crank to generate voltage and measure electrical resistance as an indication of insulation quality in equipment such as motors, generators, and switchgear.
    These testers have an analog display that works well for measuring rapidly changing resistance values because you can see the magnitude and rate of change more easily than on a digital display.

    Insulation Testers for Hand Tools

    Image of Product. Front orientation. Insulation Testers. Insulation Testers for Hand Tools.
    Ensure proper insulation and ground wire continuity in new or repaired drills, circular saws, grinders, and other hand tools. Also known as a hi-pot tester, it checks the quality of a tool's insulation by applying voltage and measuring how much current leaks from the tool.
    Calibration Certificate—The calibration certificate is traceable to NIST.
