Decoding Surface Finish Gages and Parameters

Long-wavelength waviness and short-wavelength roughness require a wide variety of instruments and parameters for proper measurement — and lower numbers aren’t always better.

Matching Thickness Gage Types to Proper Applications

Different thicknesses require different gage types during inspection — four common ones are handheld indicators, handheld micrometers, opposed air streams and gage blocks.

Choose the Correct ID/OD Gage for the Task

Benchtop and portable comparator gages each have their place, but the differences are more than surface deep.
