Metrology Gages

Our metrology gages measure to the millionth of an inch (1/3500^th of a human hair), a fraction of a micron or a single arc second (1/3600^th of a degree). For ultra-precision performance, ease of operation and unmatched reliability, industry, government and research facilities around the world choose ABTech gages.

Every metrology gage is U.S. made, manufactured by ABTech at our Swanzey, New Hampshire, facility. Every gage reflects ABTech’s high quality standards: Our rotary and linear air bearings deliver the smoothest friction-free motion and years of repeatable, maintenance-free measurements. With state-of-the-art engineering and robust materials (including hardened stainless steel, cast iron and granite), our metrology gages measure your parts to the tightest tolerances.

You can depend on ABTech for metrology gages that:

• Meet certified micro-inch accuracy levels, giving you confidence in your measurements
• Feature non-contact air bearing components requiring no maintenance or lubrication over their lifetime
• Are designed with thermal stability and vibration isolation, minimizing outside influences that can affect measurements
• Efficiently use a minimal air or nitrogen supply
• Can be customized to meet the most challenging measurement applications

Our metrology gages are grouped into two general categories:

• Form measurement: Compares your part to ideal references for runout (T.I.R.), roundness, squareness, concentricity, cylindricity, parallelism and radius measurements
• Dimensional measurement: Compares your part’s deviation from known sizes (for thickness and length)

Other gauging solutions manufactured by ABTech include quality tool room and inspection-style gage stands; fine adjust tilt and center worktables; granite surface plates; welded steel bases; precision translation stages; and part holding fixtures.
