    Commercial Refrigeration and a digital manifold.

    Is anyone else using a digital manifold such as a Fieldpiece or Testo for Com. Ref. work?

    I'm still old school. Mechanical guages, digital thermometer and a T/P chart.

    I've adjusted several EPRs after Techs had dialed them in with your mentioned method. That's the reason I ask.

    I have used both and own the field piece. I dont find myself using them as often as I thought I would. I will say they are nice to to check sub cooling and super heat at the same time.

    I've been using my AK900's for a while and don't ever see going backwards to the old school method . . Except when using my stubbys on critically charged stuff.

    Been using Digi-Cool 1200 & 1250 everyday for a few years now in Supermarkets. I've put tens of thousands of pounds of refrigerant through them and probably a little over 200 gallons of oil.

    In the freezer, dropped, kicked, stepped on, bounced around in the back of my van.

    Still work great.

    I don't see myself using a standard manifold, a dual input thermometer, and a PT chart ever again. Where's the altitude adjustment for the PT charts printed for sea level?!

    Been using my DC 900's for last two years in resi, comm, ind & refer work. Along with my stubies, I'm in heaven.
    Now if I can find hoses that can stand toe-to-toe with my DC's! Any sugestions?

    Digi-Cools 1200 and 1250's for years. They take a beating and keep going.

    Just got the Digi-cool AK900's. they are great so far. Had the JB digital gauges and after 4 repairs at $ 100 each and they broke again I had enough. There's a reason why they were discontinued. They would keep sending me new ones and there would always be something wrong. Once I didn't even get away from the sales counter and they stopped changing refrigerants, they were stuck on R-22. Needless to say, stay away from them...

    I'm using NRP ball valve end hoses. They're pretty good. No complaints.
