    Are you talking about something like this?

    I'm not a fan of Supco but I would find it useful. Testo has a similar one but it looks too expensive and flimsy imo.

    Also are you getting good feedback on your wireless system?

    Thanks for posting that. I haven't seen that one.
    RTD sensor with .2 ˚F surface temp accuracy
    Its worth a shot. I'll let you know how it works.

    That's ok are far as it goes, but there's no air temps with that, so not really.

    I received mine a couple days ago. Pleased with the performance. Responds as fast as my Fluke 52 and pipe probe. It is accurate, though does not show in tenths of a degree . The little piece on the battery cover broke the first time I put a battery in.

    Is the metal sensor fixed or does it slide into the case when measuring?

    Russ,

    Thanks for allowing us to help to develop the tools that we need to do our job better.

    Here is a product that I like but just does not last. I have been through 3 of them in less than a year and will not buy another one.
    http://www.ebay.com/itm/4005I-Cooper...08845941013808
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    It is fixed. It is larger than I expected. I am sure they gave the dimensions, I guess it just didn't register. The battery cover broke first time I put a battery in. The box talks about a cover but there was none just the device. I am very happy with its performance though. Seems as fast as my Fluke but does not display in tenth's of a degree. I got the "hi" temp version, I think it is 250 degrees. It is handy, I really am just using it on pm's. If I suspect a problem I go for the Fluke 52.

    In order to measure evaporator superheat you would have to measure the pressure and the temperature at the same location as there is a pressure drop in the line between the suction service valve and the evaporator outlet.

    When I want to check the superheat at the outlet, AI typically pump down the system and install a braze in access fitting at the evaporator outlet. Later if the service requires service this is also a great place to install your vacuum gauge.

    If you remember the old Sporlan T& P charts if you measured suction pressure at the condenser you had to add 2-3 psi to the reading then convert to saturation temp to determine the superheat. This however is only a guess. A kinked suction line, short radius fittings, not reaming the line, under sizing or excessive length would all impact performance.

    Why did they used to do that? Systems were engineered. Today they are to often just "built".
    JLB,
