Small electrical instruments

The original insulation testers came in two boxes, separating the voltage generation from the measurement circuit, to avoid electromagnetic interference problems. It was some time later that they were combined in a bakelite box with the iconic handle for driving the dynamo. Five years later the low resistance ohmmeter (LRO) was invented, these became known the world over as Ducter
testing. Housed in wooden cases, these testers had a long and admirable history, in fact Megger has been given an early LRO that was still in calibration in 2006.
In 1923 Megger was brought the idea of the multimeter by Donald Macadie. Measuring amps volts and ohms in a single instrument was revolutionary and the AVOmeter model 1 was born. 85 years later the last model 8 mark 7 came off the production line and Megger is launching the AVO800 range of multimeters

In Macedonia all big energy-companies (MEPSO, EVN, ELEM) are using Megger insulation testers. Also all the small hydro-power-plants, Industrial customers , transformer manufacturers MAKITEL Ohrid, Rade Koncar and all Inspection companies use mainly Megger instruments.
Megger offers a wide range of tough, high quality hand-held instruments which are used to test electrical wiring and other components in domestic, commercial and industrial facilities and other general business operations to the 18th Edition of the wiring regulations.
