    TPI 122 Palm-size Digital Multimeter

    The TPI 122 Palm-size Digital Multimeter is a compact multimeter that measures electrical variables including AC voltage (600V), DC voltage (600V), and resistance (2kΩ) as well as testing wire continuity. A choice of four range/resolution options for DC voltage (three for AC) ensure precision whilst basic DC accuracy stands at ±0.5%.

    Readings are displayed on the TPI 122’s clear digital display and it is operated through a clearly labelled dial. Test leads and a tough rubber case with a tilt stand come supplied as standard and the meter is covered by a three-year manufacturer’s warranty. A 500-hour battery life complements the small size for maximum practicality and it is safety-rated Cat II to 1000V and Cat III to 600V.
