(L.S. Starrett Co.: Athol, MA) -- L.S. Starrett Co., a leading global manufacturer of precision measuring tools and gages, metrology systems, and more, has introduced a custom designed and manufactured Chordal Height Gage (a.k.a. DO Gage) to be used for measuring the opening heights of turbine vanes at specific locations to verify that an aircraft engine will get proper airflow. The new Chordal Height Gage is part of the Starrett line of special area flow gages.

Even with the availability of hundreds of standard precision tools and gages, sometimes measuring challenges are best solved with a specially made gage. So, Starrett’s special gage division designs and builds dimensional measuring instruments that provide guaranteed performance to meet customer specifications.

“Generally, to take turbine area flow measurements, an operator must take the nozzle off the production line and bring it to an automated inspection machine, such as a CMM. However, the special Chordal Height Gage allows for rapid in-process verification of these parts, eliminating time lost on additional teardown and setup of machinery,” says Kyle Webber, Starrett special gage division engineer.
