Micro-Ohmmeters - Ductors

For very low resistance testing, for example welded joints, switch gear and switchboard components where contact resistance needs to be vary accurately tested, the obvious choice of instrument is a micro-ohmmeter, which is often referred to as a "Ductor" tester. These instruments use a test current from 10A up to 200A, and we even have one model which can output a test current of up to 1,000A. Unlike a milli-ohm meter, the micro-ohm meter can measure very low resistance much more accurately as a result of their higher current output. We have a full range of AEMC micro-ohmmeters and also the latest MIKO range which are specifically designed for industrial use in the high end Australian market.

For general 10A low resistance testing, the AEMC 6240 and the AEMC 6255 are overwhelmingly popular with most clients. For a lower priced alternative, the SEW 9010UO offers a full 10A micro-ohmmeter at a much lower cost. The AEMC 6292 is a 200A micro-ohmmeter designed for use in high voltage scenarios.
