For dozens of years, the James G. Biddle Company in Pennsylvania manufactured test equipment under its own name. Biddle was also the main importer of Megger products for many years. Since 1889, Megger has been a major provider of electronic test equipment in England and around the world. The test equipment that Biddle manufactured included multimeters, insulation meters, resistance meters, data acquisition (DAQ) instruments, battery chargers, calibrators, and high potential (hipot) tests. Megger eventually acquired the Biddle Company and continues to manufacture high-voltage equipment in the Biddle name. ValueTronics is proud to sell used and refurbished products from the Biddle brand.
