Nitrogen purge flow meter for brazing hvac pipes

A look at my nitrogen purge meter, i got it from a welding supplies store, its the type used on Mig and Tig welders for the sheilding gas, think it cost around £18 a couple of years ago, i also got a dedicated regulator as my other one goes up to 700psi for safety testing R410A stuff, think this one tops out at 150psi which is much safer for a purging set up. The other thing is an oil drain pan, the type you'd use to drain your car engine oil into, its a great thing to use to drain vac pump oil into or even your truck if your want to save some money on servicing bills! If you do decide to get one, make sure it has propper sealing plugs for the drain holes, some types have designs that would leak if it overturned in the work truck. Its best to drain the vac pump oil when its nice and hot, give the pump a couple of two second runs when its empty to get any oil out of the chambers before refilling.
