(OP)
I am looking into getting a portable Rockwell tester (some of our forgings are too large to put on a tabletop and would be more convenient as far as batch sizes go) any suggestions as far as brand or style? Also, any insights to the ASTM E110 spec would be helpful.
Thanks Y'all,
JC

PS: Do you find issues with surface roughness with the Equotip HTs

If you are dealing large forgings, why aren't you using a Brinell tester? The King Portable Brinell tester is a mainstay in the forging business and I would generally trust a King Brinell result more than a Portable Rockwell. True, even a King tester is operator dependent (and I have seen more people mis-use portable testers more than I've seen them use them correctly), but it is much easier to train someone to use one over a Wilson M-1. With Brinell, you have to have a good surface, or you can't read the impression, which makes it a bit more fool-proof. Of course, having to read the impression is more difficult than reading a dial (or, I guess, perhaps digital readouts with today's technology), but it isn't that difficult to do.
I've used the Equitip testers quite a bit, too. They are good for letting you know if a material is hard or soft, but if you needed to know if a part is 30-36 HRC, I'm not sure I'd trust them. Either the M-1 or King tester can give you that confidence.

I agree Equotips are good .Going back to basics there is the Telebrinell.
I think you are going to try several yourself to find what works in your appication.
