    retiring the old school manifold gauges---going wireless

    After fooling around with gauges- and thermometers taped to the high/low- and so on- I decided to go with wireless or at least digital that calculates the super/sub and pressures- and the correct charge (more needed/less needed)---its just a huge time saver. I weigh the refrigerant tank before and after- not during.

    what recommendations would you make? I've seen some that interface with an app- and others that are sort of self contained- but It seems none of them are universally loved- or hated- but there are some that seem to have quality issues. I'm perfectly happy with gauges- but as we get more and more refrigerants- I either have to keep changing the gauge- or buy new manifold- and I use the hilmor 4 valve- so those are expensive--just to buy because I need to use a special gas or my gauge doesn't have a particular gas.

    recommendations? Advice?

    I'm in the same boat as you as far as digital gauges or wireless in place of the standard manifold set. I have friends that like the SMAN 460 and I have enjoyed using it but I still cant make my mind up yet. Will be glad to see what others have to offer on this.

    X2 on the aks. Currently the last year plus Ive been using the yellow jacket p51-870 I believe. Its got the color touch screen. Gives you everything on one screen but what I really like is how it reads. I feel like Im still looking at my analogs. It has the app, Ive never used it though. They seem to be built well. My biggest worry was the screen which has not been an issue. Battery life is good. Really no complaints here. They arent bad to read in the direct sunlight also.

    Heres a picture.

    Id recommend SMAN 480v with the wireless temp clamps and smartphone app which allows you to save site records. Though they are a tad expensive, its an excellent gauge set.

    I have read about the complete wireless set from fieldpiece(JL3KH6), do the SMAN hooked to the wireless temp probes and psychrometer work pretty well. I like that idea a little better than going full wireless as of right now.

    The fieldpiece JL3KH6 is the way to go. I have the imperial manifold set as well but i find that it is way to bulky

    Toying between the sm480v and the yellow jacket p51-870. Can anyone show a pick of each next to a set of analog gauges. Leaning towards the yellow jacket because of the size and the manifold itself looks better built however the 480v also has a lot of great features yet I feel the 480v is going to be bulky.

    If you want slim and sleak, take a look at Testo.

    I have 2 sets of model 550s. Ive had no issues.

    Ive also given 3 sets to apprentices, and 2 other co-workers have bought them also.

    No issues.

    The 4 valve models and those with built in micron gauges seem to have more issues.

    I have watched a few videos on the testos but havent got my hands on any. I would like to try them out and also the fieldpiece wireless kit.

    Testos wireless I think would be perfect for any pm/troubleshoot, but always need something with a manifold to add if needed.

    I loved my old digicools until they died 😭

    But I replaced them with the fieldpiece 380v and my oh my, these are amazing, especially with their app or measurequick, I've never been soooo pleased with a purchase I've ever made. Really well thought out set of gear 👍

    The YJ P51 is a great tool, it has thermistor temp probes that are wired, vacuum gauge is seperate from the manifold and really great, reads right with my BluVac Pro. I have nothing bad to say of the YJ, but it's not up to the FP 380/480.
    I use the 380, with JL wireless temp probes and psychrometers, and it is THE best manifold I've used and I use to be a AK900 user. These blow it out of the water. To have EVERYTHIING right on the screen in front of you in real time is fantastic. It even reads the FP scale so yo can automatically keep track of how much refer you've put in. Logging is fantastic and I normally use the JL app to calculate TEET to see delta T over the coil. I won't be using anything else.
    For history, I've used AK900, earlier SMAN, Testos, and YJ P51, nothing compares.
