    new manometer for gas pressure

    I am looking for replacement manometer for my Test 510s.

    I want them with displays, not other device dependent.

    Single port would probably be okay, as I have others for static.

    Thanks

    I really like The Fieldpiece SDMN5

    But if you need uber accuracy, then Fluke 922

    If you want to old school it, Dwyer Magnehelic with a portablility kit.

    -5” to 5” is the ideal range for resi natural gas equipment.

    For LP, you’ll need something with a bit more range, so Id recommend a second magnehelic with a higher range for that.

    Plus 1 for SDMN5. Or 6 if you want a finicky feature you will probably never use.

    Ive got both the Testo and the FP.

    The FP I like alot, cause you can measure 2 pressures simultaneously and scroll between the 2, and it displays differential at the same time.

    The 510 is differential only.

    The Supco, I dont have. It may be a decent meter, but I see that same meter branded 50 different ways on Amazon, so I doubt its anything to write home about.

    Dwyer makes some bulletproof digital manometers, they are built like tanks. http://www.dwyer-inst.com/Product/Pr...eters/Digital/ A bunch of different ranges and accuracy specifications, single and dual port.

    I noticed that, too.

    Those are decent and I have a few, the biggest issue is no back light on the display, and you have to buy the protective boot separate if you want one. But they are fairly accurate.

    I'm a bit confused on the website descriptions. Do they all do negative pressure? Seems like NONE specify negative, just 0-whatever positive pressure.

    Whatever I get I would like it to be a possible back up to my meters for static readings so it needs to do negative as well.

    Dwyer website says:
    The SERIES 475 Handheld Digital Manometer measures positive, negative, or differential pressures of air and natural gases in ranges from 1 in w.c. (0.249 kPa) to 150 psid (10.34 bar).
    The Series 476A Single Pressure Differential Pressure Digital Manometer can be used to measure low pressures from -20 to 20 in w.c. with ±1.5% FS accuracy. The Series 478A Single Pressure Differential Pressure Digital Manometer can be used to measure positive, negative, or differential pressures.

    Be careful which one you buy.

    I like the SDMN5 because it actually has two independent pressure sensors. Even my iConnect dual port manometer only uses 1.

    The only thing I don't like is the drift, but you get that with a lot of digital manometers unless they are very expensive. The high end manometers use a built in solenoid to auto zero at set time intervals. My Testo 420 balometer uses this type of manometer.
    The other down of the SDMN5 is the max is just under 2psig.

    The CPS bluetooth dual port didn't work well for me. I think it only uses one sensor as well.

    Analog Dwyers are always a nice back up.

    My old fashioned go to device: Yellow Jacket 78075... Always works and no flutter.
