At The Gage Lab, we intentionally use the spelling “Gage” rather than “Gauge” because in the manufacturing and metrology industries, “gage” specifically refers to precision inspection tools used to verify the dimensional accuracy of parts.
While “gauge” is the more general term (used for pressure gauges or measurement dials), “gage” has long been the accepted industry term for the specialized tools and systems that ensure products meet exact specifications.
In short:
Gauge = general measurement instruments
Gage = precision inspection and verification tools
Our name reflects our focus: dimensional measurement, precision, and performance.
