Discipline 01

Dimensional Measurement

Calipers · Micrometers · Bore Gauges · Height Standards

Every dimensional tool in your crib carries a drift budget. We measure it, document it, and bring each instrument back inside tolerance — with a certificate that names the uncertainty at every range step.

Inspection StepPass Criteria
Zero-point verification at 68 °F ± 1 °F≤ 0.00005″ deviation
Full-range linearity sweep (5-point minimum)R² ≥ 0.9998
Repeatability & reproducibility (GR&R)< 10% study variation
Anvil flatness & parallelism checkWithin 0.0001″

Discipline 02

Pressure & Vacuum

Gauges · Transducers · Manometers · Vacuum Sensors

Pressure instruments drift under thermal cycling and process shock. Our dead-weight tester references provide a primary standard that eliminates comparator uncertainty from your audit evidence.

Inspection StepPass Criteria
Dead-weight tester reference at 5 ascending points± 0.025% FS
Hysteresis check (ascending & descending)< 0.1% FS
Zero-offset confirmation post-bleed≤ ½ graduation

Discipline 03

Torque Instruments

Wrenches · Screwdrivers · Multipliers · Analyzers

A torque wrench that reads 5% high on a fastener joint is a liability waiting to surface at audit. We characterize each tool across its full working range against a rotating-beam primary standard.

Inspection StepPass Criteria
Clockwise accuracy at 20%, 60%, 100% of range± 4% (ISO 6789-2)
Counter-clockwise accuracy (if bi-directional)± 6% (ISO 6789-2)
Repeatability — 5 consecutive readings per pointCV < 4%
Mechanical condition: click mechanism / scalePass / Adjust
Angle encoder verification (electronic models)± 0.5°

Electrical & Electronic

Multimeters · Clamp Meters · Oscilloscopes · LCR Bridges

Electrical test equipment drifts at the amplifier and reference level. We calibrate to manufacturer specification using a Fluke 5522A multi-product calibrator — the same reference your OEM used at factory acceptance.

Inspection StepPass Criteria
DC voltage accuracy — 5 ranges± 0.01% of reading
AC voltage accuracy — 4 frequencies± 0.05% + 5 counts

Audit Evidence

In-House vs. Calibrate

The gap between a calibration sticker and a defensible certificate shows up at audit — not before. Here's exactly where in-house programs lose ground.
