Professional Height Gauge Calibration Services
In precision manufacturing, the vertical accuracy of your measurements defines the quality of your output. At DRS Technologies, we provide expert height gauge calibration services to ensure your instruments maintain the strict tolerances required for layout work and part inspection. Our technicians calibrate a wide range of height gauges, from traditional vernier models to high-end motorized digital systems, ensuring absolute reliability in your metrology lab.
Why Accuracy in Height Measurement is Critical for Production
A height gauge is subject to wear on the base surface, mechanical play in the column, and degradation of the electronic sensor or dial mechanism. Even a microscopic deviation can lead to out-of-tolerance parts and failed quality audits. Regular calibration by DRS Technologies eliminates measurement uncertainty and ensures your equipment complies with ISO 9001 and other international quality management systems.
Our Technical Height Gauge Calibration Process
DRS Technologies employs high-grade reference standards and controlled environments to verify your instrument through a comprehensive protocol:
-
Surface Plate and Base Inspection: We verify the flatness of the height gauge base and the condition of the surface plate interface to ensure stability.
-
Mechanical and Column Alignment: Our team checks for perpendicularity and smoothness of travel along the column to identify any mechanical binding or wear.
-
Linear Accuracy Verification: Using NIST traceable gauge blocks or laser measurement systems, we test the gauge at multiple points across its entire vertical range.
-
Repeatability and Hysteresis Testing: We perform multiple measurements at the same height to ensure the sensor or dial returns consistent results every time.
-
Certification and Traceability: We provide a detailed calibration certificate featuring as-found/as-left data, measurement uncertainty, and a clear chain of NIST traceability.

Frequently Asked Questions Regarding Height Gauge Calibration
What is the recommended calibration interval for height gauges?
The standard calibration interval for height gauges is twelve months. However, if the gauge is used in a high-volume production environment where it is subject to constant movement and contact, a six-month interval is recommended to prevent measurement drift.
How does DRS Technologies ensure NIST traceability for height gauges?
Our laboratory uses gauge blocks and master standards that are calibrated directly against NIST-traceable equipment. This provides a documented, unbroken chain of measurement comparisons, ensuring your height gauge readings are accurate and legally defensible.
Can the probe of the height gauge affect the calibration?
Yes. The diameter and sphericity of the probe tip are critical for accurate measurements. During calibration, DRS Technologies inspects the probe for wear and ensures the software or dial is correctly compensated for the probe’s physical dimensions.
