TUV Nel
NEL has been at the forefront of engineering development and innovation for more than 60 years.
The company was established in 1947 under the auspices of the UK Department for Trade and Industry (DTI) and quickly gained a reputation as a world-wide centre of excellence for engineering and mechanical research.
We were responsible for the development of British Standards for the safety of climbing ropes and worked on improving the efficiency of F1 Motor Racing brake fluids. We have been involved in flow system testing for over half a century and maintain and develop the UK's National Flow Measurement Standards.
