Diesel Engine Compression tester advice/suggestions.

I work as a Heavy Duty Mechanic and I'm just now starting at a shop that does alot of engine repair. I've also got my own heavy equipment and truck.
I'm gonna need to compression test a Cat C-12 in my own truck so i'll need an adapter for that to start.

Does anyone have suggestions about a good compression tester kit to buy that has adapters to deal with all the major engine types and platforms?
