The Megger Ducter™ DLRO100 enables low resistance measurement, across multiple applications, in areas without access to mains power. The integral Li-ion battery supplies a constant 100 A current for up to 200 automatic or manual tests enhancing productivity in remote locations.
With a focus on user safety, advanced design features ensure the safe operation of the instrument in the most adverse conditions, including a CAT IV 600 V safety rating in accordance with IEC61010. A DualGround feature is available on the DLRO100X and DLRO100H, which adds to the operators’ safety by grounding both sides ofthe breaker under test.
The tough design, intuitive interface and IP54 (lid open) rating ensure reliability and ease-of-use in the most arduous of conditions.
History of ‘Ducter’ testing
For over 100 years the ‘Ducter test’ has been used to describe a simple test for measuring very low contact resistances and “Ducter”, which is still used as a trade mark, was the name originally given to the low resistance ohmmeter manufactured by Megger. The name Ducter was registered by Megger in June 1908 and ‘Ducter’ has since become the industry standard.
