BB1, servicing a regulator "in the field" is not something that is done often, if ever. The point is to do preventive maintenance so you don't need to worry about your gear in the field.
I for one would not service a regulator in the field. And lets see how your tune goes when you tear apart a reg full of corrosion. Ultrasonic is pretty much the only tool that will clean the threads, bores, and crevices inside a regulator body.
And yes, I know a far amount about measuring pressure, I worked at a company that makes high accuracy pressure transducers for 5 years. And I have spent the last 9 years in aerospace.

I'm also quite meticulous in how I like things done, so while it's taking me time (and $$) to learn to do it myself, at least I know who screwed it up if things go wrong 
). There really is not a whole lot inside a regulator or tank valve that you need a special tool for that you can't make a more standard one "work" it just might not be quite as "convenient". Kinda like how some of these people would burn $300+ for anodized aluminum -AN wrenches for aluminum -AN hose fittings....All you needed were your standard wrenches and not act like an idiot with them(IE over torquing and just being generally careless scratching it up). Or one of my all time favorites was a guy that needed a tap wrench to use a 3/4" NPT tap and went out and bought a $200 monster tap wrench just for this when all he needed was a 1/2" drive t-handle and an appropriately sized 12 point socket that would have cost him $20 max
