Master Instruments Pty Ltd is a 100% Australian owned and operated manufacturing, importing and distribution company employing a staff of approximately 70 people.

The company was established in 1942, primarily to manufacture electrical measuring instruments for the three Australian Defence Services.
Commencing in a small way, the company soon established itself as a leader in its field by the desire to excel in the design and manufacture of electrical instrumentation. Today the company is still a quality supplier to the Defence Services as well as to Telstra, other government instrumentalities and private enterprise.

Our head office and factory is located in Marrickville (suburban Sydney) in a modern brick complex and consists of approximately 2000 square metres of fully equipped manufacturing assembly lines, warehouse, tool room, machine shop, laboratory & R&D room, meter clean room, printing & drawing room & administration offices. Recently our Melbourne branch was relocated to Ringwood (suburban Melbourne) to accommodate production & warehousing requirements. The company also has long standing representative relationships with distributive offices in all other Australian states and regional areas.

The company diversified in the early 1980's into battery pack manufacturing & assembly and now stocks Australia's largest range of primary and secondary cell batteries & battery packs. Specialised portable test and measuring equipment, process control instrumentation & electronic equipment assembly are also still part of our product range.

Master Instruments represents most of the world's leading battery manufacturers and sets the benchmark for product & application knowledge in the south pacific region. Although well established and widely recognised, as we commence our 64th year in business, the same drive for excellence to produce goods of quality at an affordable price is still maintained.

Master Instruments Pty Ltd is proud to stand behind its reputation of quality, reliability of products, performance and service to Australian industry.
