The Seaward LLT live line tester is a voltage detector ideal for live line testing on systems up to 1100V DC, and is encapsulated in a high impact rugged enclosure with high-visibility cable. The unit is fitted with high-intensity red LED indicators and a polarizing filter making it clearly visible, even in direct sunlight.

Designed and manufactured in compliance with international safety standard BS EN61243-3, the live line test unit is totally encapsulated in a shock resistant high impact rugged enclosure and is IP65 rated. The tester is also equipped with PVC hand guards and high visibility cable.

Designed specifically for live line applications, the LLT high voltage indicator ensures conductor rails have been isolated from the power supply before maintenance or inspection work commences on rail track systems.
