B&K Precision helped pioneer the electronic testing industry, and like so many early electronics firms, B&K started in a garage. By 1948, when Americans had begun buying televisions in large numbers, Chicago entrepreneur Carl Korn and his partner Philip Ban responded to the need for maintenance of often-unreliable sets. Frustrated by a lack of equipment to easily test television components, Ban and Korn began making their own devices and opened Central Television Service Company. They soon had a thriving business selling CRT rejuvenators and vacuum tube testers to other television service shops. By 1951, Korn had developed what would become B&K Precision into a company that had branched out into other areas of electronic testing and measurement. B&K engineers broke new ground, earning several patents in the field of television test equipment, and rapidly pushing the company to become a worldwide leader in electronic measurement.

In 1961, Carl Korn placed B&K Precision under an umbrella corporation, Dynascan, comprising a variety of electronics firms. One of those companies, Cobra Electronics, came to dominate the Citizen's Band (CB) radio phenomenon. Choosing to focus on radios, Korn sold B&K Precision. Through an ensuing series of ownership transitions B&K continued to produce high-quality testing and measurement products.

In 1996, engineer Victor Tolan, headed up a new ownership team for B&K Precision that launched a greatly expanded product line. The company also expanded upon its American base to better serve international customers. Company headquarters moved to southern California to provide improved service to Asia. In 2004 B&K expanded its presence in Europe through the acquisition of Sefram Instruments to better meet customer needs in the region.

B&K Precision has come a long way from its days in Carl Korn's garage, but holds fast to the business ideals of innovation, flexibility, and solid customer service that have guided us from our humble beginnings in America, while reaching out to embrace the rapidly expanding global marketplace. We now provide service and support on four continents, and our design team draws upon resources in places as wide-ranging as Romania, Israel, and Taiwan.
