Amprobe was founded in Long Island, New York in 1948 as the Pyramid Instrument Company. Less than two years later, in September 1950, the company was awarded its first patent for the Clamp-on Inductive Ammeter. It became so well known for these meters, the company name was formally changed to Amprobe Instrument Corporation in 1960. Amprobe was acquired by the Danaher Corporation in 2006 and moved its worldwide headquarters to Everett, Washington.
Today, Amprobe's rugged, well-built products range from an extensive line of clamp meters and digital multimeters, to industry-specific tools that address the needs of professionals in HVAC/R, power quality, water quality and solar energy.
