About us

SenTek was founded and incorporated in 1999 to provide measurement systems and services to the metals industry. We offer thickness and coating weight sensors and scanners, X-ray and isotope sources and services, engineering and obsolete-part replacements, along with a strong team of dedicated factory and field service technicians to help our customers day or night. Our list of satisfied customers is growing steadily.

SenTek designs, builds, and tests measurement systems for customers worldwide. Our 16000 sq. ft. [1500 sq. m.] facility in Columbus, Ohio, includes manufacturing, assembly, offices, laboratory, and training facilities.

We stock many common and uncommon parts for new and legacy gauging systems. In order to keep our prices low and avoid long delays we purchase most of our components locally. Our Emergency Parts and Service support is always available 24 hours every day.
