    Hello guys.
    I comparing manometers. The range varies from 5psi, 15,30, and 100 psi. The brand is SPER.
    What range do you think I should get.
    To be honest, never needed more than 3.5" WG lol

    I would appreciate your input very much.
    THANK YOU

    Hungry,
    Your a student, I wouldn't come on here, bad mouth a professional member and ask about something that is used to indicate inches of water colum, and ask it's range in psi.

    As doc as said , without being a numb nut, they don't measure psi.

    You don't need to be defensive, if you mean something else
    ask it, or stay a student and stay HUNGRY.
    If you try to fail, and succeed.
    Which have you done ?

    Considered a digital manometer? I'd get the Testo 506-3 if you don’t own anything else and $165 is in your budget. I like because its quick easy and no fluids.

    I think the dual range (low to 4 WC and hi to 80 WC) covers most of your need - even has a pitot tube option. 3 decimal places on the low scale (that’s no the accuracy of course).

    The units of measure are anything you want about and easily selected on power up.

    It does have PSI. Check out the web site.

    I was going to go Dwyer and a get real manometer but decided it would pay for itself over time.

    Get a Dwyer, I have had mine for about 7 years. Look for something that will read at least 20" w.c. Mine will read up to 20" w.c, and can select scale if I need PSI, Mbar, pascal etc.

    I usually use "w.c., or pascal when I check house pressures.
    4 pascal is easer to understand/explain to a customer (when dealing with house pressure) than telling them .016"w.c.

    You'll need more than 3.5". You may want to check pressure drop across hea t excahngers, duct system static pressures, pitot tube readings.

    Also get a dual port so you can read total pressure as well. Also look for a resolution of 100th's (0.00) for the low end readings.
