Full Tank Analyzer

[JediCheese]

I am researching the various DIY Nitrox/Trimix analyzers on here and realized that I have a few old 1st stages sitting around. Has anyone combined a 1st stage with a digital pressure gauge and an analyzer all in one? It would be bulkier than only an analyzer but would also allow a log of the whole tank (PSI, CO, Helium, and O2).

Less helpful on a boat but nice at a shop when picking up tanks to verify that you're getting what you want.

I use an old reg attached to an SPG and a BC inflator hose. I plug my analyzer pressure reducer into the BC hose. Just add a longer analyzer / inflator hose, and the analyzer can stay on the bench or in the rack.

same here - I've used an older regulator with a full size SPG & inflator hose, and also used an Argon bottle regulator that just had a button gauge on it. I also keep a short wooden dowel in my analyzer kit to release the pressure from the regulator (so I don't damage the Schrader valve by jamming a knife or other metal object in there )
