Anyone know where I can buy a propane gas low psi pressure gauge, that is not $40.00 and up? Most of the cheap ones are for water pressure, or for air. I was going to buy three of them, one for each piped line for my three burners, so I could see at a glance if pressure is holding for safety, before lighting the pilot lights on brew day.
1/2 psi is all that the gas gauge has to read but I think the smallest psi range they sell is 0 to 15 psi. Will a gas pressure gauge used on welding tanks work?
