Arnold Gauge has been solving production measurement problems since 1918. What began with Philip S. Arnold’s in-process grinding gages has grown into a broad range of custom, bench, hand-held, automated, and grinding measurement systems.
Our history
More than a century focused on practical measurement
1918: the first Arnold gages
Henry Ford asked quality engineer Philip S. Arnold to improve the quality of automotive parts. Arnold developed in-process grinding gages in the basement of his home and founded Arnold Gauge in Flint, Michigan.
1973: a new Ohio chapter
The Bruns family brought Arnold Gauge to the Cincinnati area and expanded the company’s capabilities beyond grinding gages.
Today: custom measurement systems
From simple GO/NO-GO tools to robot-loaded inspection systems, Arnold Gauge combines proven gaging principles with modern controls, automation, and data needs.
What we do
Engineering support for difficult gaging applications
Our work starts with the part, tolerance, process, and people who will use the gage. We focus on a solution that can be operated, maintained, and trusted in the production environment.
Custom gaging
Application-specific fixtures and systems for dimensions or features that do not fit an off-the-shelf product.
Production integration
Manual, semi-automatic, and automated concepts that bring inspection closer to the manufacturing process.
Grinding measurement
In-process grinding gages, parts, service, and support built on the company’s original specialty.
Experience across industries
Built for real manufacturing environments
Arnold Gauge has tackled measurement challenges in aerospace, medical, automotive, technology, energy, defense, and consumer-product manufacturing. More than 75,000 Arnold gages have been delivered since the company was founded.
