I use the JB SH-10N it's a great meter and have checked it against the Fluke temperature clamp very accurate and it does the math for you. http://www.jbind.com
I use the J/B SH-31N. Wouldn't leave home without it! I actually have it strapped to my center manifold gauge hose. Works beautifully. This is my second year using the gauge without any problems. Constantly displays superheat or subcooling depending on how you have it connected. Let me know if you get one. I'll try to take a pic of mine and post it. I use it on every job that my gauges get connected to. An investment you won't regret.

I also use the SH31N a perfect tool for a perfect job everytime......you wanna be accurate....you wanna be 100 % positive..its a must saves 45 minutes on every job for me.
Just got my new SH-31N J/B superheat subcool gauge I love this thing its great!! dont know how I did this with out it. But then I had to buy a new Yellow Jacket manifold and a new set of Imperial kwik-coupler. Thanks HVAC-Pro, Topdog, hvac/r-ia
need to see pic on how too hook up,have one in shop some where,was told by rep that on the micron gauge you cant use your refer hoses with it,while you are pulling a vac,it sucks the oil out of your orings leaving tiny pin holes in them,i think he said you have to use a piece of copper some conn,oh well in the draw it went.any other suggestions on hook up?
if at first you dont succeed,then skydiving is not for you
