Our organization started in 1995 when business innovators EMCO, Rantec, and Ray Proof merged their assets to develop EMC Test Systems. While our development is new, the sources of each organization operate seriously. Ray Proof began as a provider of healthcare X-ray protecting in 1932. Rantec guided in the advancement of anechoic absorber and microwave chambers for the army during the early 1970s. EMCO (The Electro-Mechanics Company) established as a result of magnetic industry and radio frequency analysis in the 1960s.
