Martindale VT28PD-S Voltage Tester & Proving Unit Kit
The Martindale VT28PD-S Voltage Tester & Proving Unit Kit is a comprehensive solution for safe isolation procedures.
The VT28 is a rugged, compact two-pole tester that measures AC/DC voltages from 12V to 690V. It features bright LED indicators for voltage levels and includes a continuity test function with a buzzer. Additionally, it can perform single-pole phase tests and phase rotation measurements.
The PD690SRD Proving Unit is part of the kit and provides stepped outputs at 50V, 120V, 230V, 440V, and 690V. It ensures the proper functioning of the VT28 and meets GS38 compliance requirements.
The kit fully meets the requirements of GS38 and proving dead procedures and comes in a heavy denier carry case for convenient storage and protection when not in use.
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 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 before commencing work.
