    Manifold Gauges Are Obsolete

    Everything I work on now has transducers and thermistors. Why do I need gauges?

    Gage are always accurate.
    More reliable than gimmicks.
    Don't need battery.

    And if you live up north display will freeze.

    Tool ain't making the technician.

    Just my feelings this morning.

    How would you add refrigerant?
    "Right" is not the same as "Wise".

    Don't step on my favorite part of the Constitution just to point out your favorite part.

    I have been using these (Carel) since 2002. What I have found is they're within 1% of my gauge set, and I have never had a bad one, only a bad cable or moisture in the plug. Bad cable or connection issue they read -623 in the controller.
    Totally trust them, because everytime I thought they were wrong, they were spot on.

    I work on all different brands. I've found transducers from 3-50 psi off. Trust, but verify......

    I never find that on the refrigerant side, but I do on the water side.

    Like electric test meters, digital or analog, there are times to have both.
    Give me a relay with big enough contacts, and I'll run the world!

    You can be anything you want......As long as you don't suck at it.

    If a person wants to create a machine that will be more likely to fail...Make it complicated.

    Ive replaced 15 or so carel transducers in the past 5 years.

    Everything is destined to fail at some point.

    I do agree, they are spot on when they work
