Overhead view of sensing elements used for food service applications

Today’s fast food and restaurant chains rely on their equipment to eliminate downtime and maximize efficiency. In this industry, downtime can result in spoiled food and lost revenue. That’s why the world’s largest chains work with manufacturers who supply products that require as little service as possible.

At QTI, we understand what food service manufacturers are up against. At our in-house Test and Validation Laboratory, we optimize sensor reliability to help ensure that equipment operates properly when you need it most—reducing service calls and warranty costs for all of our customers.

QTI has the expertise to be an integral part of your design process, from engineering to validation and manufacturing. If you can dream it, we can build it. Contact us today to learn more about QTI’s wide range of custom solutions.
