Our Story

Founded by Wes Harford in 1999; AM Sensors Ltd became one of industry’s valued instrumentation suppliers. Our rebranding to AMS Nuclear in early 2019 reflects the evolution of the company; from trusted instrument supplier to that of a highly reputable and respected engineering company. Still operating in the southwest but from modern offices in Bridgwater, Somerset; our committed engineering teams provide technical advice and end to end engineering solutions for EC&I Systems, Environmental Sampling Systems and Ageing & Obsolescence issues.
