Noncontact hardness testers, looking for recommendations
I am looking for a portable, noncontact, hardness tester that I can use to measure the Rockwell of saw blades.
I found a couple online but I can't find anybody to give me a quote.
So I guess I'm looking for a unit as well as a knowledgeable, responsive source.
I appreciate any help you cared offer.

RE: Noncontact hardness testers, looking for recommendations
Here are three approaches to the problem. The first is the Eddy currant probe. I'm not sure about the Richter instruments which are rebound instruments and may or may not leave a mark. The third is the Ultrasonic hardness tester,
i haven't personally used any of this type but have been around to check the results on the Eddy Current type and the Richter.

Cant comment on eddy current testing

Strangely enough I was told that rebound and ultrasonic types do not leave an indentation. Once I pressed the person a bit, the answer became more along the lines that they do leave an indentation but nothing like the conventional testers do.
Thank you for the heads-up,
Tom

There may be methods that can tell you hardness is OK by somehow detecting another property that correlates with hardness.
