Stay Audit‑Ready With Gauge & Gauge Assembly Calibration, & Certification

Precise, Traceable Measurements for Safe, Reliable System Performance

What We Offer

Professional Calibration, Repair & Certification

Restore accuracy and compliance through controlled environment testing and professional calibration of gauges and gauge assemblies.

Complete Internal Inspection

Every gauge and assembly undergoes thorough internal inspection of bourdon tubes, movements, sensors, and components to uncover hidden issues before they impact performance.

Restored to OEM Accuracy

Instruments are adjusted and calibrated back to original manufacturer tolerances, with “as found” and “as left” data providing full visibility into performance changes.

NISTTraceable Calibration & Verification

All calibration services follow NISTtraceable processes to support regulatory compliance, QA programs, and audit requirements.

Documentation & Certification

Clear calibration certificates, test data, tagging, and compliance documentation provide traceability and confidence during audits and inspections.

Tagging & Identification Support

Proper labeling and identification support asset management, maintenance scheduling, and long term reliability planning.

Maintain safe, compliant, and efficient operations with Galloup’s professional calibration and certification services for gauges and gauge assemblies. Our team restores your instrumentation to manufacturer-level accuracy through controlled environment testing, NIST-traceable processes, and comprehensive inspections. You can count on dependable readings that help you run your process with confidence and peace of mind.

The Risks of Gauge & Gauge Assembly Calibration, & Certification Failures

Accurate measurements are critical for process control, equipment protection, and safety. Galloup eliminates the risks caused by drift, damage, or improper calibration practices through precise, thoroughly documented service.

These are the issues we eliminate before they reach your facility:

Drift in Accuracy Over Time

Wear, fatigue, and environmental conditions cause gauges to lose accuracy. Regular, traceable calibration restores confidence in your readings.

Noncompliance with Regulatory Standards

Industries requiring NIST, ISO, or ANSI compliance depends on certified calibration. Our processes meet these standards and provide full documentation.

Hidden Internal Damage or Component Failure

Issues inside bourdon tubes or movements can go unnoticed until they affect performance. Our inspections expose these risks early.

Risk of Hazardous Operating Conditions

Inaccurate gauges can cause overpressure, system imbalance, or unsafe equipment behavior. Calibration prevents these dangerous conditions.

Unplanned Downtime or Product Loss

Faulty readings lead to system inefficiency, shutdowns, or production issues. Reliable calibration helps maintain uptime and consistent performance.

Lack of Documentation for Audits & QA

Many facilities require traceable records. We provide complete calibration reports for compliance and traceability.
