About us

Turnkey Instruments Ltd

Turnkey Instruments Ltd is a leading designer and manufacturer of quality industrial and scientific instrumentation ranging from heavy vehicle brake testers to air quality monitoring equipment. Over the years we have gained a reputation for supplying reliable, easy to use, instrumentation to a wide range of industries especially mining, quarrying, rail transportation and the World’s police forces. Since all our products were designed and developed by us we understand them completely and the Service and Calibration support we offer for them is second to none. We simply don’t have to rely on other manufacturers to serve our Customers.

Turnkey Instruments Ltd was founded in 1990. Initially it had one product and just one employee. The company moved to Gadbrook Park, Northwich in September 1991 and today we have over 10 in-house products and 15 employees. We also have subsidiary companies in Australia and South Africa, together with sales agencies in numerous other countries throughout the World.

Our sister company, Turnkey Products Ltd, was formed in 1994 to carry out the manufacturing operations for Turnkey Instruments. It also offers a contract manufacturing service to other companies.

Our companies are known collectively as the Turnkey Group, and in March 2000 the Group obtained its ISO9001 Quality Assurance Certificate.
