Brand Megger

This version of the Megger LT300 Earth Loop Tester ships as standard with a set of fused leads and clips. There are also two other models of this tester available that ship with a mains plug and non-fused leads.

The LT300 offers high current loop testing over a wide range of frequencies and supply voltages with simple, fast, two wire operation. It has a large clear display that aids visibility in poor conditions. The high current loop test provides fast accurate and stable results with a resolution to 0.01Ω on the 20Ω range.

The instrument is housed in a rubber armoured case with a built-in cover to protect the display when not in use. The IP54 weatherproof rating provides excellent protection in adverse conditions.
