Our History

Alltronics LLC is based in Silicon Valley, California and has been supplying electronic, electromechanical and test equipment since 1978. AnaTek Instruments was incorporated as a family-owned business in New Hampshire in 1991. In 2007 Anatek partnered with Bob Parker in Australia to produce the distinctive and popular "Blue" ESR and Ring Tester Meters. In 2014 Anatek was acquired by Alltronics LLC and we continue to proudly offer the "Blue" range of component testers and also sell many other new and surplus parts for electronics hobbyists and professionals.
