I'm not looking for an argon regulator. I looked in the description and it says "For use with 100% Argon and Argon/CO2 mixed gasses." Why does it make life easier to stick with a nitrogen regulator? I thought Tired Horse said using an argon regulator wouldn't matter. I just can't find a nitrogen one that has lpm and a hose barb on it. Is it that you have to recalculate the lpm meter?
For reference, this is what I'm referring to what Tired Horse said: "Harbor Freight Tools offers a cheap CO2/Ar regulator (it also works for N2) with a flowmeter that shows flow in both Cfh and Lpm and goes high enough for our purposes. This is what I have."
I also have some other questions.
How do you tell how full a cylinder is by looking at the pressure gauge? Do I go by the service pressure? So if my 40 cu ft nitrogen cylinder has a service pressure of 2015 psi, that means the gauge should read 2015 psi if it's full, half of that if it's half full, a quarter of that if it's quarter full, and so on? I'm also confused about the difference between the service pressure and the test pressure. Which one do I go by? Because the test pressure is 3000 psi.
Is it necessary to use a hose clip/clamp?
Should I be skeptical of the service/test pressure values given by these two websites because they look like they are offering the exact same product but the service/test pressures they give differ from each other:
New 40 cu ft steel nitrogen cylinder with CGA580 valve. Solid, reliable nitrogen tank ready for use in beverage, HVAC, and industrial applications.

New 40 cu ft nitrogen cylinder in steel. Perfect for beer mix/G-mix use. Great mid-capacity nitrogen cylinder that delivers exceptionally fresh beverages.

You have to look under "Specifications" for the first website and "Additional Information" for the second website for the service/test pressures. The first says 2524 psi/3365 psi and the second says 2015 psi/3000 psi.
