Is anyone using - or do you know of anyone using this type of portable hardness tester? - see link below - model Qualimag DR

http://www.worldoftest.com/portable-hardness-tester-magnetic-type-qualimag-series

We would like to buy/use but the issue is that I am not finding anyone using it- so that I can have some feedback - manufacturer is quite difficult to obtain information.

Thank you in advance.
I have not used that specific model, I have used something like this and had to return it. I found out it was designed for large, non-portable material. At the time, I did not know hardness testing required that 'massive' of parts. Our parts are too small for portable hardness testing.

What kind of hardness tester you are using right now. I am looking for a hardness tester and our products are also small , general surgical instruments like forceps and scissors , clamps, rongeurs etc.

phoenix, if your parts are too small for Rockwell hardness, the only reliable way to get a hardness reading will be by sectioning, mounting and polishing and measuring using Vickers microhardness.

Depending on the geometry of your parts, you may be able to get a Vickers hardness reading on the surface; my experience has been that surface measurements often differ from measurements done on cross sections.

Hope this helps.
