I found a 125# recovery cylinder full of; what I believe to be R-22. We have about sixty 25 ton R-22 units. My question is: What is the safest most reliable way to test the cylinder's refrigerant for acid? I would hate to take in $600 worth of potentially good refrigerant. We typically use Sporlan test all kits with the compressor oil; however, in this instant I am unsure how to go about this. I have read a lot of mixed feedback about the vapor tests.

Qwikcheck

a co-worker of mine picked up a six dollar qwikcheck "2-second acid test"...

I'm already skeptical. The company who makes this thing is called: Mainstream Engineering.

Usually when a company names themselves in such a way as the name suggests a quality or attribute they seldom live up to the expectations the name promotes.

ex. Pro choice.

I like the idea of pumping the vapor into a separate tank with a catch-all inline filter. We have several 50# tanks I can jump the refrigerant over to and our local supplier has agreed to trade the 125# tank for two 50# tanks. Since all our package units hold about 40# i'm of the mindset of never having to lug around that 125# tank... ever.
