  • Pressure measurement for stationary and portable applications
  • ±3% accuracy
  • Gauge fluid included
Inclined liquid manometers are capable of pressure measurements above and below atmospheric as well as differential pressure measurements, and are economically priced, compact and available in both stationary and portable configurations. Construction is simple with virtually indestructible molded white styrene-acrylonitrile housing, indicating tube and fluid wells, molded ABS knobs and zero adjust plunger, shock mounted glass level vial and leak proof 'O' ring seals. These manometers are very easy to use - simply fill the reservoir, adjust fluid level to zero, connect the tubing, and the gauge is ready for operation.

Curved inclined-vertical tube of model 68062-58 provides higher ranges with more easily read increments at low readings and is excellent for general purpose use.
What's Included:
Red gauge oil

  • Q:

    is the specific gravity of product number SN68062-62 is 0.826 at 200C
    Asked on 10/9/2012 by Michael from Sri Lanka

    1 answer



      The specific gravity listed in the MSDS is 0.826 and based off ambient temperature - about 20C. 200C is beyond the flash point of this fluid (about 72C).

  • Q:

    Since automatic transmission fluid and red gauge oil look exactly alike and have the same specific gravity; and since transmission fluid cost $5.00/Qt. vs $12.00/4 oz for gauge oil, why can't I use transmission fluid instead of gauge oil?
    Asked on 10/7/2012 by commonsense guy from Waynesboro, GA

    1 answer



      The fluid may, or may not, be chemically compatible with the tube/wetted parts, and although the specific gravity is the same it does not mean the viscosity and other physical properties are the same or that they will provide the same readings.

  • Q:

    How often is it necessary to add gauge oil to a Dwyer Mark II Inclined Liquid Manometer?
    Asked on 7/6/2009 by Anonymous

    1 answer



      After a couple of years you may have to add some oil due to evaporation. As a general rule of thumb, if you can zero the unit, you don't need to add it.

Comments about Dwyer A-102 Red Oil Gauge Fluid, 4 oz, 0.826 SG:

I purchased a manometer for reading low differential pressure on a filter bank. The manometer came with fluid but I was not informed of this. So I bought this bottle of fluid. did not need it for the manometer I bought, but was given another that the fluid is now being used in. Good fluid. Works well. Happy with purchase.

    Comments about Dwyer A-102 Red Oil Gauge Fluid, 4 oz, 0.826 SG:

    Product does what it is designed to do very well. But, my order (P.O. 56662) asked for one bottle which arrived OK, but then another bottle showed up about a week and a half later and was invoiced with the same PO again. We payed for the second bottle instead of going through the hassle of returning it.
