Martindale VT28 Voltage Tester

The Martindale VT28 shares the same useful functions as the VT25 but has the additional benefit of an LCD display. All voltage, continuity and phase rotation indications have the same bright LED indication but the VT28 also displays the measured voltage reading on the 25mm x 15mm LCD display. The large digit LCD display of the VT28 gives actual voltage readings in addition to the LED voltage ranges. The AC/DC voltage detection, continuity and phase rotation functions all have bright LED indication. Auto power-off ensures a long battery lifetime. The voltage indicator conforms to the latest safety standards and includes removable probe caps for GS38 compliance. Additional safety features include a double insulated 1.2m cable with a black outer and contrasting inner core to give a visual warning of damage. FEATURES 12 - 690V AC/DC. LED & LCD Voltage Display. Single pole phase test 90 - 690V. Phase rotation test 100 - 690V. Continuity - optical and acoustic indication. Auto power off. White LED torch light.
