Since 1937, Loy Instrument has earned a reputation as one of the Midwest’s premier providers of industrial measurement, automation, combustion, and process control solutions. As a privately owned engineering organization, our philosophy has remained unchanged for nearly 90 years:

Understand the customer’s process before recommending a solution.

Our engineers work alongside manufacturers to improve safety, reliability, efficiency, and productivity by combining technical knowledge with practical field experience. From instrumentation selection and application engineering to systems integration, startup assistance, troubleshooting, and lifecycle support, Loy Instrument delivers complete engineered solutions—not simply products.

With more than 800 years of combined engineering and process control experience, our team understands the operational challenges facing today’s manufacturers and provides practical solutions backed by responsive technical support.
