You can rely on ATS for high-quality granite surface plate calibrations. We understand the critical importance of using surface plates as a reference in your facility, which is why we offer calibrations to fit your schedule.
Our Process
Our technicians can inspect surface plates for surface flatness and detect variations caused by the wear and tear of everyday use. If your plate’s measurements are outside of acceptable tolerances, we can help you determine your next steps.
ATS uses a Federal Level System to produce a three-dimensional layout of your inspection table. We also check your surface plate with a repeat reading gage. The combination of these methods assures the accuracy and flatness of your surface plate. We can certify your Surface Plate to one of the following:
- Grade AA-Laboratory Grade
- Grade A-Inspection Grade
- Grade B-Toolroom Grade
After completing our services, we provide calibration certificates for all items calibrated at your facility. Register for our web-based interface, iPortal, to access electronic copies of calibration certificates, asset history, and due date reports at your convenience.
Our Qualifications
All calibrations performed in the field are traceable to the National Institute of Standards and Technology (NIST) and are performed in accordance with documented and controlled procedures.
Our labs are ISO/IEC 17025:2017 accredited. We are an ISO 9001:2015-registered company with a quality management system that complies with the following:
- ANSI/NCSL Z540-1
- 10 CFR 50 – Appendix B
- 10 CFR Part 21
