CO2 Tank Pressure Reading

[benman]

Kind of an odd question for you veteran keggers.

I went and got my 5# co2 tank filled yesterday and when I got home and hooked up my regulator (brand new) it shows the tank pressure right above 700psi. Is this normal for a new full 5# co2 tank, or should the pressure be higher than that. I'm wondering if the shop I had fill it didn't get it right as I had other issues while I was there.

What temperature is it at ?

Here is a chart i found

If it was cold it will show more gas as it warms up.

That gauge is pointless... When I fill my tank up it barely reads past 500 (get more gas)... and it pretty much stays there until it makes a sudden drop to empty.

Awesome. Thanks for the responses. The tank is at room temperature. Building my keezer tonight thought so that won't last long
