GL McGavin Pty. Ltd. Is a company that was formed in Sydney Australia in 1968, out of a need to protect electrical workers from being injured. With its state of the art product the first of many models of the Modiewark non-contact voltage detector were designed. The Australian power industry gratefully accepted this tester as a life saving device, implementing a national roll out in the early 1970’s.
From this point the Modiewark adapted it’s self to the needs of the industry, improving itself by providing self testing capabilities, voltage selectors to suit each application and accessories to perform substation spout testing and phase compatibility testing.

In 2007 a team association with a local engineer and developed a new product line of Modiewarks, The Modiewark Mini Testers providing a miniature and user friendly product allowing us to keep pace with the changing industry. Rescue departments in New South Wales Australia, took up the new rescue tester, providing their staff with a safe approach procedure. The Mini SWER and Pole tester taken in hand by Country Energy for the testing of SWER(single wire earth return) and the application of pole leakage detection which costs the industry many thousands of dollars per year. The MR tester (Meter Reader) was developed to ensure the safety of the meter readers who frequently come accross live domestic power boxes.
To ensure quality control with this safety device Pritchard Electronics became an acquisition of the Morris group providing improved technologies and in house quality control.
