Company History
The origins of TTi date from the late 1970s when two separate companies, Thurlby Electronics Ltd. and Thandar Electronics Ltd. were both designing and manufacturing electronic test equipment within close proximity at St. Ives in Cambridgeshire.
Through the 1980s, Thurlby specialised in bench power supplies, high resolution multimeters and digital storage units; whilst Thandar specialised in function generators, frequency counters and logic analysers.
In 1989 the two companies were merged into a new organisation - Thurlby Thandar Instruments Ltd. - and located to larger premises in nearby Huntingdon.
Since that date the product ranges have been expanded and new product areas developed including arbitrary waveform generators, RF test equipment, EMC measurement equipment and component bridges.
In addition to selling the TTi range of products throughout the world, the company has also expanded its UK sales operation to represent other major producers of test equipment.
Today TTi is one of the foremost producers of general purpose electronic test instruments and laboratory power supplies in Europe, selling products in over fifty countries.
It is also one of the largest distributors of test and measurement equipment in the UK representing many leading American, European and Japanese producers within the United Kingdom market.
TTi is an ISO9000 registered company and maintains the highest quality standards for all of its activities.
