At Accurate Instrument Repair, we are experts in the calibration of cylindrical ring gages and are accredited to ISO/IEC 17025 and ANSI/NCSL Z540

We have over 30 years experience in the calibration of precision cylindrical ring gages. We first began calibrating precision ring gages with the original Pratt & Whitney Ring and Disk comparators back in 1982. Now, we use state of the art Pratt & Whitney Labmaster Universals. This is a direct measuring system that is laser based and is designed to accomplish the same job as the comparator in less than half the time. Using direct measurement eliminates unnecessary standards and much of the human contact error associated with comparison measurement (e.g. gage block wringing ect.) With this system, we can also provide our customers with a lower measurement uncertainty. This combination offers you the most affordable price and accurate reporting of your calibration data.

Most dimensional lab personnel and quality inspectors use precision ring masters or ring gages routinely, but few actually know what is involved in the calibration process of their standards. Here, at our Foothill Ranch California facility, we consider ourselves the leaders in cylindrical ring gage calibration and experts in dimensional measurement.

Below, is part of our 55 page mapping process that shows just a fraction of what is involved in the accurate measurement of your ring gages. For more information please contact any one of our dimensional experts.
