    I love my cooper blue box. I'm definitely going to hop on the wireless ship at some point, but I like knowing that I'll always have an accurate meter for pipe temps and humidity/wet bulb.

    Just an example. If you have high superheat and high subcooling it suggests the system is low on refrigerant.

    It always was. AFAICT, the app is the same old app. Probably a few additions, but basically the same. I don't give much attention to iConnect's troubleshooting either.

    Also, I've heard you have to have a data or wifi signal to open the app. Once the app is open, you don't need it anymore. I haven't had a situation where I haven't had data yet. So I can't say if that is still an issue.
    Allegedly, they've fixed that. You only need a connection to sign in to the app when you use it for the first time, thereafter, none needed until perhaps, an update.

    The air probes seem accurate after a dozen or more uses. They both read exactly the same in the same air stream.

    I have a couple Cps Proset Avt45 T fittings in the bag to use to charge the system with the probes attached.



    It's gives a great amount of information. Here is the info given for the air measurements. You scroll down to get all the refrigerant info.
    There have been a few complaints of inaccurate calculations, but that's from a while back. Have you noticed any? Thanks for the info.

    No, I haven't noticed any accuracy issues. But honestly I've only used them about 10 times so far.

    I tested them again today. Both the same reading sitting side by side. So either they are both accurate or off the exact same.

    That sounds like a nice device, but a little too much going on for me. I could definitely see military applications. I may look it up though.

    Relatively inexpensive compared to the competition with decent ratings.

    I use the fieldpiece dual in duct. Works great. Love that it takes enthalpy readings so I can see if my air flow is truly right.
