RHEINTACHO UK, which was formerly called Foundrometers Instrumentation, was founded in 1919 in Leeds. It acquired Harding of Leeds in 1980. In 2000, Foundrometers was in turn taken over by RHEINTACHO Messtechnik GmbH of Freiburg, Germany, founded in 1901. This combined history of over 300 years makes a unique combination of history, tradition, innovation and experience available to its customers, suppliers and employees alike.

RHEINTACHO UK manufactures mechanical and electrical products to measure, control and monitor rotational speed ranging from handheld mechanical tachometers, eddy current tachometers, tacho generators and indicators. It is also the competence center within the company for ATEX products, which are intrinsically safe for use in hazardous environments. The Spares & Repairs division of RHEINTACHO UK can refurbish, service or reengineer any older device, regardless of the age or manufacturer.

RHEINTACHO UK also serves as the official trading partner of its parent company within the UK and Ireland. The portfolio includes a wide range of inductive and hall sensors to measure, monitor and control rotational speed. The second pillar of products are the stroboscope, available as portable and stationary units in LED and Xenon versions. They are among the highest performance strobes worldwide.

Finally, there is a division for optical and digital tachometers to measure and monitor rotational speed and linear movement.
