Application fit
When to Choose Height Gauge Measurement
Choose height gauge inspection when the part can be referenced on a flat surface plate and the required dimensions are vertical, stepped, datum-related or layout-oriented.
- Vertical dimensions, shoulders, step heights or feature offsets need fast verification.
- First article, in-process or final inspection requires traceable dimensional data.
- CNC setup, fixture alignment or tool height checks must be confirmed before machining.
- 2D coordinate layout, scribing or datum transfer is needed on a granite surface plate.
- Measurement should be faster and more economical than full CMM programming.

Resolution, Accuracy and Calibration Standards
Reliable height gauge inspection depends on the measuring instrument, granite surface plate, datum setup, operator technique, gauge block verification and report traceability.
| Requirement | Typical Planning Range | Inspection Notes |
|---|---|---|
| Resolution | Standard 0.01 mm, high-precision 0.001 mm | Choose based on tolerance, surface finish, feature access and report needs. |
| Accuracy | Typical 300 mm model accuracy around +/-0.01 to +/-0.03 mm | Final capability depends on equipment, calibration, setup and operator technique. |
| Datum reference | Clean granite surface plate, stable part seating and controlled zero setting | Datum quality often determines repeatability more than display resolution. |
| Calibration cycle | Annual for general workshop use, 3-6 months for precision QC programs | Adjust frequency based on usage, environment, damage risk and quality system. |
| Traceability | Certified gauge blocks, calibration records and documented measurement method | Supports ISO 9001, IATF 16949-style documentation and customer audits. |
