Over the last 20 years Unitest has been providing electrical test equipment to the WA mining, utility and contractor markets. Combined with our experience and knowledge of testing and measurement we have also provided training courses to make sure the operators are confident and competent. We back that up with our own local service and calibration workshop.

The two partners in the business, Lindsay McInnes and Trevor Dinsmore have both had backgrounds in electrical engineering and test and measurement with Lindsay spending many years with Siemens both here and overseas, while Trevor was WA sales engineer for the long established Nilsen Instrument group.

Whether it's looking for advice and direction on Underground service locators, Earth testers, Power recording equipment, HV VLF and Hipot testing, Micro Ohmeters, Insulation testers or Installation testers to name a few, we have the largest range of reputable brands and models in WA with prices to meet every budget. 

We have given ourselves to being personable and understanding and meeting the needs of customers as we circulate across the broad area of the electrical industry and are always willing to share that knowledge and experience to help meet the demands of modern testing requirements. For that reason we are building a collection of application notes for publication on our website which are freely available.

Many of our customers are long term repeat business companies, for we understand that trust and integrity is critical in all aspects of selling products into the market. So please feel free to browse through our website and contact us by phone or email if you have any questions.
