Tech-Aid Products is a company which is dedicated to providing quality Avionics And Instrument shop test equipment to the aviation community. Since our first product design in 1990 to the present day we have maintained this commitment. Over the years we have developed some products that we feel are very beneficial to aiding the technician in his everyday repair efforts. The test panels we build have the technician in mind as we try to insure that all switch labeling is done for functionality and not by number alone. This approach we feel will promote greater efficiency and a better understanding of equipment functionality when testing that equipment. We are confident that we can provide your shop with a quality product at a competitive price, whether a new design or an existing one. One of the outstanding features on our panels is the use of Lexan overlays with back side silk-screening that will never wear off or deteriorate and therefore that new look will remain for years.
