A part is also something I can then use when I move up a size, which might be happening sooner now and using the system on that as I can get the Ista bottles refilled cheaper or any CGA320 bottle infact.A 600g disposable would last quite a while on a tank that size. I can see the problem Andrew though yo want something that looks ok as its visible Not easy
Dual gauge regulators have two pressure gauges, one is cylinder pressure and other output pressure. The cylinder pressure, for CO2, will always typically read 800psi/55bar as long as there is liquid CO2 in the cylinder. The output pressure gauge typically will read to 5 bar (70psi), typically 2.5bar is OK for CO2 injection. This may or may not be adjustable depending on your regulator, mine is fixed at 2.5bar and I have never had any issues injecting CO2.So as I'm now a bit in the wind, what defines a dual stage regulator?
Thanks @ian_m
I understood (in a fashion) the difference but unsure there is a way to tell for sure without having things apart is there?
I will guess that it's just a dual gauge and not dual stage and assume 'tank dump' is something I would only find out through trial.
Time to toss a coin, return as (probably) misinformed or stick with the Ista.
