Kewtech KT1780 Two Pole Voltage & Continuity Tester

Kewtech KT1780 Two Pole Voltage & Continuity Tester

The Kewtech KT1780 Two Pole Voltage & Continuity Tester provides AC and DC voltage testing up to 690V together with continuity testing in one practical instrument. Bright, oversized LEDs give a clear indication of voltage levels, while an audible tone provides additional feedback during testing. The tester also includes polarity indication, a single-pole phase test and phase rotation indication for three-phase systems.

Designed with electrical work in mind, the KT1780 uses UK-specific GS38 slender probe tips that fit into recessed terminals without the need to unscrew caps. Its double-moulded grip gives a comfortable hold, while the probe cover helps protect both the user and the probe tips. A bright white LED pen torch provides useful illumination when working in dark or poorly lit areas.

The Kewtech KT1780 Two Pole Voltage & Continuity Tester meets IEC 61243-3 and IEC 61010-1 safety standards and carries an IP65 rating for resistance to dust and water. Automatic power on and off helps simplify operation, and a built-in self-diagnostic test provides an additional operational check. With phase rotation testing, continuity measurement and clear visual and audible indication, it brings several routine electrical test functions together in a compact handheld design.

Key Benefits

• Checks both AC and DC voltage up to 690V with clear LED indication.
• GS38 slender probe tips provide easier access to recessed terminals without removing caps.
• Bright oversized LEDs make voltage levels easier to see during testing.
• An audible tone gives clear feedback for continuity and voltage indication.
• Single-pole phase testing supports quick phase presence checks from 100V to 690V AC.
• Phase rotation indication assists with checking left or right rotation on three-phase systems.
• Polarity indication provides an additional visual check when testing DC circuits.
• The built-in white LED torch improves visibility in darker working areas.
• IP65 protection helps guard the tester against dust and water ingress.
• Automatic power on and off and a self-diagnostic test support straightforward day-to-day use.
