1986 - 2024 ACT Meters - 38 years

"In 1986 when Halley's comet last appeared, ACT Meters was borne after an invention by David Grant of the world's first radio-linked digital multimeter enabling remote circuit testing by one engineer. 30 years on, the family owned business has grown to become famous worldwide for its innovative test equipment and battery testers. When Halley's comet reappears in 2061, who knows what star ACT products will have been invented!"
