A ring gauge is used to measure, verify and/or calibrate gauge diameter sizes. Ring gauge kits are offered in sizes ranging from 0.0625” up to 4.0” and are available with standard steel blocks or for abrasion and corrosion resistance choose zirconium-based ceramic blocks. These kits are perfect for maintenance personnel and technicians, as well as beginner and professional users. Purchasing tools in kits, versus individually, offers considerable savings as well as helps ensure you have easy access to various sizes and types of tools for all of your projects. For the most accurate measurements, we can provide NIST-traceable calibration services for your gauge blocks. In addition, we can source these products from manufacturers beyond what you see on our website or in our catalogs.

Calibration Gauge Block Kits are available with steel blocks or zirconium-based ceramic blocks that are abrasion- and corrosion-resistant. Block sizes range from 0.0625" to 2" (9-piece set) and 0.10005" to 4.0" (36-piece set). Kits include a protective wooden case, and NIST traceable Certificate.
