Originally formed as Everett Edgcumbe, High Voltage Instruments Ltd. has been at the forefront of test instrument design since it’s formation in the year 1900. Since then the company name has changed to Edgcumbe Instruments Ltd and the Metrohm brand was created.
The Metrohm brand is held in the highest esteem internationally for product quality, innovation and value for money. Following a management buy-out in April, 2007, the Metrohm range of High Voltage products designed by Edgcumbe Instruments were added to the High Voltage Instruments Ltd portfolio.
Starting from 2007 the company has been operating from Glasgow, Scotland. Following a takeover by T&R Group in November 2020, High Voltage Instruments manufacturing facilities were moved to a more spacious, top of the line manufacturing complex located in Guildford, Surrey, in 2022.
