About us

Founded as Everett Edgcumbe, High Voltage Instruments Ltd. has been a pioneering force in test instrument design since its establishment in 1900. Over time, the company underwent a name change to Edgcumbe Instruments Ltd. and introduced the Metrohm brand.

Internationally renowned for its exceptional product quality, innovation, and value for money, the Metrohm brand enjoys a prestigious reputation. In April 2007, following a management buy-out, High Voltage Instruments Ltd expanded its portfolio by incorporating the Metrohm range of High Voltage products, originally designed by Edgcumbe Instruments.

Since 2007, the company has been headquartered in Glasgow, Scotland. However, in November 2020, after a takeover by T&R Group, High Voltage Instruments' manufacturing facilities were relocated to a state-of-the-art and larger manufacturing complex in Guildford, Surrey, in 2022.
