We provide on-site optical comparator calibration. We calibrate all makes and models of optical comparators, including Starrett, Mitutoyo, Nikon, Tamarack, Scherr Tumico and more. We calibrate each optical comparator at five points per axis and/or at custom test points established by you. All calibrations are traceable to the International System of Units (SI), established by the International Bureau of Weights and Measures, through the National Institute of Standards and Technology (NIST). We can perform the optical comparator calibration either on site at your facility or at our calibration laboratory.

Our calibration services documentation and test reports show calibration information such as "as found" and "as left" data, next scheduled calibration, etc. We are continuously adding standards that facilitate our commitment to maintain our customers satisfaction.
Customers can rely on us to keep accurate records of all instrument calibrations. If any certificate of calibration is missing or has been destroyed by the help of our customer support agent you can get a duplicate certificate. We have historical documentation on our units dated back to the early part of the 20th century.
All our calibration services are directly traceable to N.I.S.T. Our primary Calibration Standards are sent for calibration, in accordance with N.I.S.T. requirements and based on regular schedule as defined by our Quality Assurance Manual. Only approved laboratories and N.I.S.T themselves are used for these calibration services.
