Hello I just got my single gauge co2 regulator in today. An I was take a look at actual gauge it self an notice where the needle on the gauge rest there that there are only 3 marks from that point to 10psi I am wondering what those marks are counted as here a pic https://imgur.com/a/GdtGq
I would interpret those 3 marks as 4, 6, 8 psi. Not sure where 2 went?
2 1/2, 5, 7 1/12 ??
I agree with @voodoo_donut. I will also opine that 2 is not on there as it is so insignificant and not worth reading. The only time you would use 2psi is to push beer, which is easy enough to see that you don’t need to know it’s exactly 2psi.
