Metrology


What is a Metrologist?

A Metrologist...
"Develops and evaluates calibration systems that measure characteristics of objects, substances, or phenomena, such as length, mass, time, temperature, electric current, luminous intensity and derived units of physical or chemical measure. Identifies magnitude of error sources contributing to uncertainty of results to determine reliability of measurement process in quantitative terms. Redesigns or adjusts measurement capability to minimize errors. Develops calibration methods and techniques based on principles of measurement science, technical analysis of measurement problems and accuracy and precision requirements. Directs engineering, quality and laboratory personnel in design, manufacture, evaluation and calibration of measurement standards, instruments and test systems to insure selection of approved instrumentation. Advises others on methods of resolving measurement problems and exchanges information with other metrologist personnel through participation in government and industrial standardization committees and professional societies."

What does this mean to you? At Actco Metrology, your work is in the hands of professionals who know measurement. While formal education in the quality field is not only important but necessary, we have found that there are no schools on inspecting your parts!

For this reason, we have developed an aggressive "hands on" training program which focuses on perfecting the actual application of our optical and contact equipment on a variety of customer supplied parts. Combined with formal training in inspection practices, this gives you, the customer, the best of both worlds.

Contact us today to become "your" local professional in dimensional metrology.
