About Us

About Us

A business Licence for trading under the name Alectromix was obtained by Joe dos Santos in 1982 when our first Instruments were sold. Test and Measurement Instruments C.C. was later established in 1985 at a time that instruments moved rapidly from analogue to digital form, and associated itself in a long term relationship with an innovative designer / manufacturer of such quality equipment to this day and whose products are widely featured here. This has been the inspiration for our superb new T+M Instruments product range in a growing world market, and has been making it’s presence known at a fast pace by their unparalleled quality and competitive pricing, presently being marketed globally, indicating that it’s price and features are highly acceptable.
