Graham-White Air Gauge Tester - CO2 Cartridge Question

Joe Nugent · **Posted:** Thu Mar 31, 2022 11:42 am

Greetings! Does anyone have experience with Graham-White's model 706-000 air gauge tester? I'm specifically wondering if it requires Graham-White branded CO2 cartridges, or if another off-the-shelf cartridge would work as well. We found a supplier with a three week lead time on the cartridges, but I'm looking for some something I can purchase within the next week or two. (I didn't have much luck reaching GW's customer service department this morning, so I figured I'd throw this question out there...)

Any insight is appreciated. Thanks in advance!

Looks like a standard CO2 cartridge to me?

My experience is from 35 years ago, but back then, the salesman touted the advantage that their Carbon Dioxide cartridges didn't use a standard thread size, and so could not be used in employees' paint ball guns.

I think they are pretty cheap. Could just buy some and see if they fit. If they can't even attach then you could take them back.

I have not had to order them, but I have been told the Graham-White's will only work with the Graham-White tester.

I've used that model tester many times. As long as the CO2 cartridge is of the right pressure, it should work just fine.
