Why You Need a Reliable Caliper Calibration Provider
What is Caliper Calibration?
Caliper calibration compares your measuring instrument against precision gage blocks with documented traceability to NIST. We verify measurement accuracy at multiple points throughout your caliper’s range, documenting any deviations from specified tolerances. This process establishes whether your instrument meets performance specifications and provides the measurement data necessary to demonstrate compliance with your industry requirements. Accredited calibration certificates also include as-found and as-left measurements, and uncertainty analysis.

Benefits of Regular Caliper Calibration
Audit Preparedness – Current calibration certificates
with NIST traceability provide the documentation auditors
require when reviewing your quality management system.
Measurement Confidence – Regular calibration verifies
your dimensional measurements remain accurate,
supporting confident quality decisions and reducing risk
of accepting out-of-specification products.
Cost Control – Scheduled calibration prevents measurement errors that lead to scrap and rework while identifying
instruments drifting out of tolerance before they cause
production issues.
Risks of Neglecting Caliper Calibration
Compliance Failures – Missing or expired calibration
records create audit nonconformities that can delay
product releases or require corrective action plans.
Questionable Data – When calibration records are
expired, all measurements taken with those instruments
become questionable, potentially invalidating batch
records and requiring product holds.
Hidden Quality Problems – Uncalibrated instruments
may drift out of tolerance gradually, creating systematic measurement errors that remain invisible until calibration
reveals the problem.
