I was wondering if i could make some sort of charging scale for some small under counters. I was think about doing a charging cylinder that would hold like 2 lbs of liquid, or 6 ounces. they can vary in size and volume. Maybe a peice of 1 3/8 pipe capped off with valves on either end. I have heard of the same thing but it is glass, that can be exspensive. Any ideas? Thanks

Hi Tocoldtohold

I think I know what you are talking about. My old boss used to have a couple of these, they are not used these days.

Just buy a pair of portable scales and a big bottle then you will never run out.

Chillin:) :)

What are these things called? Can anybody link it? I just thought it would be fun. I need something to do with my time. I am always looking for crazy things to make or experiment with. Thanks for the huge reply. Is there nobody on the forum at night? Sorry im a noob here.

They were also known as Charging Cylinders. Only worked with single refrigerants though.

Here's one to look at....

I have one that I have found invaluable in the past. Has scales for R-12,22, and 502. Works well if you want to charge a Pound or less into a system.
I have not used it in some time, as I am an Industrial guy for the most part. I guess I could convert the scales to the new refrigerants.
I found it in a secondhand shop and the owner had no idea what it was for.

Hi NH3LVR, I have the same charge cylinder for use on
R12, R22 and R502. In the last two weeks I have sent some e-mails to Robinair distriution partners in England and Germany if I could change it to work with R134a. But no one has come back to me with a reply. Like you all my work now is with Ammonia systems.
