Amprobe Instrument Corporation has been in the business of manufacturing reliable, rugged test equipment and measurement tools for more than 65 years. Professional HVAC technicians and electricians trust Amprobe for its high-quality equipment – especially clamp meters and multimeters. Amprobe got its start in 1948 as Pyramid Instrument Company. One of its first products was the Amprobe clamp meter. In 1960, Amprobe Instrument’s name was nearly synonymous with the popular Amprobe meter, so the company changed its name. Today, Amprobe manufactures and distributes more than 500 products worldwide. Find new, used, and refurbished Amprobe flexible clamps, multimeters, and recorders at ValueTronics.com.
