Portable Hardness Testers
(OP)
We'd like to test the hardness of a generator shaft after a shrink fit assembly. The generator is about 200kg and is difficult to test on a regular Rockwell tester. I'm considering renting a portable hardness tester but have no experience with them. Are they reliable? How accurate they are? Any specific types or brands you can recommend? Thanks.

I use a portable kit from : http://www.mcmaster.com/
It is part number 1342T13 and currently sells for just under 700 bucks. Its advertised accuracy is +/- 1.5 HRC
It's accuracy is highly dependant on your eyesight, but I would say I can determine within 2 points fairly easily.
I have found it to come up with readings very close to my regular machine.

Now I have to sell the idea to my manager. Thanks.

We have also experienced people using the machine on an alloy which does not have a hardness conversion scale available, and so getting some very wrong hardness values and rejecting material as a result of this.
You should be OK if you follow the instructions, and are working with carbon and low-alloy steels.
