Established in 1974, OTEK Corporation holds a rich history tied into Dr. Fest’s work with NASA. In 1967, Dr. Fest was recruited by NASA during his senior year at IIT as one of 400,000 engineers to work on Apollo 11. Dr. Fest remained with NASA through the landing of Apollo 15 on July 26, 1971. He created a custom electric R&D company in 1972 – giving way to the birth of OTEK as it is known today.

Our products are manufactured on-site and are made to order. All of our bargraph meters, controllers, counters, loggers, and indicators are backed with a lifetime warranty. We encourage you to learn more about OTEK Corporation and how our products provide solutions to obsolescence and increase profitability with our Intelligent Instrumentation.

We are proud to be a Class 1E and Military-Spec Manufacturer in the USA.
