  • Manometers

    I have an Omega digital monometer, but thinking of changing to a better one. What do you recommend? I use mine testing gas pressure on tankless water heaters.

    Yellow jacket water u-tube manometer :-)

    Is cheap, tuff and requires no batteries or more importantly no annual calibration

      truthfully a basic "u-tube" with colored water is as accurate as it gets.

      pretty cheap and easy to calibrate too.

      the one gauge i have is pretty temperamental as it seems to be sticky.

            How do you store a liquid filled manometer? Will the liquid freeze?
            Better yet how do you read a liquid manometer?

                I use the series 1227 filled with oil and freezing is not an issue. The scale slides along the tube and u line up the meniscus with zero to callibrate and then read your pressure where the bottom of the meniscus lines up when you are checking pressure or vaccuum.
                Where I went to school use of a u-tube manometer was part of first year gas training.
                Instructions are included when you purchase from dwyer and replacement oil is also available.
                There are different u-tube manometers available depending on wether you will use oil or water due to the different specific gravity of water versus oil.
                Hope this helps.

                  Dwyer makes some nice stuff and well respected in the trade.
                  Nothing wrong with using one of them. As has been said simple,
                  accurate, and little maintenance. And no cal required for U-Tubes.
                  "When we build let us think we build forever. Let it not be for present delight nor for present use alone. Let it be such work that our descendants will thank us for, and let us think, as we lay stone upon stone, that a time is to come when these stones will be held sacred because our hands have touched them, and that men will say, as they look upon the labor and wrought substance of them, "See! This our fathers did for us."
                  John Ruskin (1819 - 1900)

                    i use the Slack TubeĀ® Manometer/Gas Pressure Kit and it came with a 1 - 3/4 oz. Bottle Fluorescein green color concentrate with wetting agent.
                    i dont think it freezes , it never did for me and it wont evaporate
