I'm Curious to know how many of you use this to test hardness. Is it worth the $100 investment? Is there a "trick of the trade" that works? Do you experienced guys just tell by looking? Also, what is the cutoff for epoxy floors as far as softness is concerned before adhesion problems occur?

Again I'm just getting into this field and want to do what's right. At the very least I believe it would go a long way in respect to being credible in the eyes of the customer. In wood restoration I use a moisture meter to make sure the deck or fence is Below 12%. A lot of businesses don't but it really helps to sell the customer on my knowledge and makes them more comfortable. But it's Also a very critical phase of the preparation of the wood.

I'm wondering if the scratch test is similar. That being, does it reassure the customer as well as being crucial to knowing if the slab is able to accept a coating and helps determine diamonds for grinding.

As a follow up question...does moisture transmission rates in a given slab vary from year to year on a significant level? Is it likely a slab that shows 2lbs one year be 6 the next and then maybe 3 later or whatever? Or does your test results indicate that particular slabs relative moisture transfer rate?

I ask because my 1st potential customer is an engineer (her and her husband are) and when i told them we were going to test for moisture and would proceed if acceptable she asked me "what if it goes up next year AFTER the floor is finished?"

Hardness testing is typically for polishers, not epoxy installers.

If you are using a diamond grinder, you will know when you hit soft concrete.

Slab moisture on a fully cured slab that's been there a while shouldn't fluctuate up much, unless something big changes. The one thing that comes to mind is the downspout gets bumped off and water pours next to the foundation for any length of time. I'm not an epoxy floor guy, so I suspect that a few PROs will chime in sooner or later and would have the experience to better guide you to answer this sort of customer question as it relates to Epoxy floors.
