Feeler Gauges

Feeler gauges are used to measure critical gaps, such as valve clearances and spark plug gaps. Over time, friction and environmental exposure can cause the blades to thin or corrode. Professional calibration ensures that each leaf maintains its exact specified thickness, preventing mechanical failures caused by incorrect tolerance settings.

For high-precision Australian manufacturing or automotive workshops, we recommend professional calibration every 12 months. If the gauges are used daily in abrasive environments, 6-monthly checks are advised to ensure that wear hasn't reduced the blade thickness beyond acceptable limits.

Yes. HK Calibrations provides comprehensive certification for both Metric ($mm$) and Imperial ($inch$) sets. We measure each individual blade using high-precision micrometers to verify they meet the required thickness standards, ensuring your measurements are accurate regardless of the unit system.

In the Australian aerospace and defense sectors, every measurement must be traceable to national standards. Traceable calibration provides a documented record of accuracy for each blade, which is essential for passing safety audits and maintaining the airworthiness of components.

To preserve the calibrated thickness, always wipe the blades with a clean, lint-free cloth after use and apply a light coating of acid-free oil to prevent rust. Store the set in its protective sleeve and avoid forcing blades into tight gaps, as this can cause permanent deformation or thinning.

A damaged or corroded blade will provide false readings and can no longer be considered accurate. You should replace the individual blade or the entire set immediately and have the new gauges professionally certified to ensure your precision work remains compliant with Australian standards.
