About Cal-Av Labs California Avionics Laboratories was established as a sole proprietorship in 1959. It was incorporated in California in 1968. The name was later shortened to CAL-AV LABS, INC In 1998, the business was moved to Tucson, and was incorporated in Arizona. Much of our effort is applied to special development projects in support of a client's ever-changing requirements, especially in research. Some of these projects become available as off-the-shelf or made to order items of instrumentation. Our remaining effort is in fulfilling orders for several lines of standard products. CAL-AV's flexibility and half-century of experience allow us to design and fabricate a broad spectrum of equipment or systems, often at relatively low cost, even for single items. We have an exceptional track record of on-time delivery.
