SPI Calibration Services
Swiss Precision Instruments across the shop floor — calibrated with the same rigor as the flagship brands.
ACS Calibration delivers NIST-traceable, audit-ready calibration for SPI instruments, available at the ACS central lab or directly on-site at facilities across the Southeast — with ISO/IEC 17025 accredited certificates available on request for instruments on our accredited scope.
SPI Equipment, Calibrated With Data
SPI calipers, micrometers, and indicators fill tool cribs everywhere — dependable working instruments that do high-volume duty on the floor while the premium brands stay in inspection. High-volume duty means high-volume wear, and SPI fleets benefit most from set-level calibration on one cycle.
We calibrate SPI instruments under our accredited dimensional scope against gage blocks, documenting as-found and as-left data per tool, with crib-scale batches returned on one due date.
ACS Calibration is an independent ISO/IEC 17025 accredited calibration laboratory. We are not affiliated with, sponsored by, or endorsed by SPI; brand names are used solely to identify equipment we service.
What You Get With Every Calibration
- NIST-traceable calibration certificate with real measurement data — not just a pass/fail sticker
- As-found and as-left readings, so drift is documented
- ISO/IEC 17025 accredited certificate with reported uncertainty — on request
- Calibration label with due date, plus a reminder before your next calibration is due
