Martindale VT28 Voltage Indicator
Designed to detect voltage between 12V and 690V AC/DC, the Martindale VT28 Voltage Indicator is a two-pole volage and continuity tester with a seven-point LED voltage scale and an LCD for displaying voltage values. A dedicated LED and buzzer alarm alert the user when continuity is detected. In addition to this, the Martindale VT28 Voltage Indicator supports single pole phase testing and phase rotation testing.
The Martindale VT28 Voltage Indicator will indicate voltage even when its battery is dead; however, an Auto-Power-Off function ensures the detector delivers a long battery life. Other practical features include a white LED torch light, GS38-compliant removable probe tips, and a double-insulated cable with wear indication.
The Martindale VT28 Voltage Indicator is a compact, comprehensive voltage and continuity tester compliant with BS EN 61243-3 safety standards.
