Allometrics operates an A2LA ISO 17025 accredited dimensional calibration laboratory where measurement uncertainties undergo rigorous third-party verification—ensuring every certificate we issue represents verified technical competence, not self-declared capability.
With over 50 years specializing in precision dimensional metrology for pharmaceutical, aerospace, chemical, and manufacturing operations, we provide NIST traceable calibration services with documented uncertainty analysis that establishes defensible measurement traceability from shop floor instruments to national standards.
Industry-Leading Dimensional Calibration Capabilities
Comprehensive documentation, including:
- Measurement traceability
- Instrument condition (before and after calibration)
- Any out-of-tolerance findings or adjustments made during service
Consistent service nationwide
- Standard 7-10 day turnaround keeps your calibration schedules on track
- 48-hour expedited service when equipment failures threaten your production deadlines or audit timelines
Precision Dimensional Calibration Across Instrument Types
Caliper Calibration
Our caliper calibration services cover dial, digital, and vernier calipers up to 12 inches, calibrated in our temperature-controlled laboratory using NIST traceable gage blocks. [1] We can measure your calipers at multiple points across their full range, document any deviations from specifications, and provide certificates showing measurement uncertainty that establishes traceability to national standards.

Gage Block Calibration
Gage blocks serve as the dimensional measurement foundation for your entire quality system—calibrating these precision reference standards requires the highest level of metrology capability. We calibrate gage blocks up to 4 inches using precision comparator equipment that delivers measurement uncertainties meeting the most demanding metrology requirements. These master standards establish the traceability chain supporting every dimensional measurement instrument in your facility. [2] Learn more about gage block calibration →
Micrometer Calibration
Outside micrometers need calibration that maintains their precision. Our micrometer calibration services deliver accredited measurement uncertainties as low as 72 microinches for outside micrometers up to 3 inches, calibrated against reference-grade gage blocks in controlled conditions. Whether you’re verifying steel component dimensions, inspecting raw materials, or conducting quality checks for aviation maintenance, our certificates provide the documented accuracy that audits and quality standards require.

Tape Measure Calibration
Allometrics provides tape measure calibration, straight edge calibration, and ruler calibration for dimensional hand tools used across manufacturing, construction, and quality control operations. Our calibration services use NIST traceable reference standards to verify linear measurement accuracy, with documentation that supports your tool calibration programs and quality system requirements.

Dial Indicators
Quality control stations, machine tool setup operations, and surface plate inspection all rely on dial indicators to detect minute variations in height, flatness, and runout. We provide dial indicator calibration services using NIST traceable reference standards to verify measurement accuracy across the instrument’s full travel range, with certificates documenting performance testing results. Whether you use analog dial indicators or digital measurement devices, we deliver the calibration documentation needed to support your dimensional measurement programs. Call with any questions about your dial indicator calibration needs
Feeler Gauges
Our feeler gauge calibration services include measurements at multiple test points using NIST traceable standards. We perform feeler gauge calibration up to one inch, providing documentation confirming the dimensional accuracy of these thin metal strips used for gap measurement in engine assembly, machine tool alignment, and maintenance applications where accurate clearance verification prevents equipment damage or performance degradation. Coordinate your feeler gauge calibration
Why Calibrating Your Dimensional Tools Is Important?
Dimensional measurements are how manufacturers know and quantify the size and exact shape of products. Therefore, precision dimensional measurements are fundamental to the interchangeability required by global trade.
Measurement accuracy is critical in the manufacturing industry, and quality dimensional calibration services provide the means for assuring the manufacturing process’s integrity.
It is common practice for manufacturers to keep records of their measurements for quality control purposes. However, over time these measurements will start revealing slight deviations from the exact size.
Unless steps are taken to correct these deviations, the deviations will continue to increase until they represent a significant financial and liability risk for the manufacturer.
Allometrics dimensional calibration services works in harmony with your quality control system to provide a cost-effective, safe, and quick way to ensure all measuring instruments, from calipers to gages, remain within upper and lower tolerances.

Dimensional Calibration Questions Answered by Our Metrology Experts
Dimensional calibration is the process we use to verify that measuring instruments like calipers, micrometers, and gage blocks produce accurate measurements by comparing them against NIST traceable reference standards. Dimensional measurements are how manufacturers know and quantify the size and exact shape of products.
We verify dimensional measurements by testing instruments at multiple points across their full range using NIST traceable reference standards in our temperature-controlled laboratory. Our process documents any deviations from specifications, measurement uncertainty values, and instrument condition both before and after calibration. Each certificate provides the traceability documentation your quality system requires.
We provide dimensional calibration services nationwide with consistent technical procedures across all locations from our ISO 17025 accredited lab. Call us at (281) 474-3329 to discuss your calibration needs. We offer standard 7-10 day turnaround and 48-hour expedited service, plus we can coordinate service timing across multiple facility locations to minimize disruption to your operations.
