30lb R134a kegs

I assume the 30lb kegs for R134a mean 30lbs of refrigerant right? Obviously the keg adds quite a few pounds.

So, could one use any scale that is accurate, precise, and has capacity for the keg, or does it have to be specifically a "refrigerant scale?" For example, starting with a full or even partially used keg of R134a, couldn't one simply watch the scale readout reduce by the desired amount? Is it that simple or am I missing something?

If you have a scale laying around that can accurately resolve down to the 1 oz level, by all means, use it. Nothing magical about a refrigerant scale.

30 lbs is net weight of refrigerant. A full one weighs about 38 lbs due to the weight of the cylinder.

Many cheap digitial scales will time out and turn themselves off during the charging time. Make sure that yours doesn't do that.

I think my jug of R134a is a 25 pound jug , net weight ?

Read a post on another forum of a person using a baby scale ?

I bought a digital bathroom scale & yes , it times out . Have to periodically lift it up and set the jug back down on the scale . kind od a pain . :-(

God bless

I recently weighed an unopened 134a cylinder to test out a new scale, & it weighed 37.8 lbs IIRC.
