    I have a question on that Jb meter Now if you are not supposed to use 22 gauges on 410 A. Why can you use that on both and just change keys on it for the refrigerant?

    The keys are so the meter displays the correct superheat and subcooling readings based on the type refrigerant you're using. It is preprogrammed for R22. The key plugs into the side of the unit. It will display up to 600 psig. and operate up to 800 psig.

    Hmm, looks like a cool tool, don't anything about keys for altitude corrections, does make a difference between sea level and 5000 feet where I work everyday or 9000 feet where I work on occasion. Just an observation.
