When Dick Henszey took over The Henszey Company that was founded in 1924, he renamed it Sentry Equipment because the company “guarded” material integrity and boiler systems against corrosion. That, with five employees and a bold vision, has grown into a global enterprise of 180 employee-owners who serve customers in over 50 countries across six continents. We deliver true representative sampling and analysis techniques to our customers, empowering them to accurately monitor and measure processes for improved production efficiency, output, and safety. Standing behind our commitments, we are determined to tackle any application, anywhere .
