Martindale VT28 Two-Pole Voltage Tester Description

Capable of measuring AC/DC voltages between 12V and 690V, the Martindale VT28 Two-Pole Voltage Tester is a compact, two-pole voltage detector with a 7-LED scale and an LCD display for indicating exact values. In addition to this, the Martindale VT28 Two-Pole Voltage Tester offers Phase Rotation, Single-Pole Voltage Detection, and Continuity (with LED and buzzer) functions.

The Martindale VT28 Two-Pole Voltage Tester is also equipped with an Auto Power Off function for conserving battery life. Other practical features include a built-in white LED torch close to the probe tips ensuring the Martindale VT28 Two-Pole Voltage Tester can be used in dark/low-light environments.

Finally, the Martindale VT28 Two-Pole Voltage Tester meets the latest safety standards. It features removable GS38-compliant probe caps and a 1.2m double-insulated cable with a contrasting inner and outer core designed to provide a clear indication of any damage.

The Martindale VT28 Two-Pole Voltage Tester is a safety-optimised, simple-to-use voltage indicator ideal for proving circuits are dead prior to commencing work.
