Dwyer 1222 series Flex-Tube U-tube type manometer uses red gauge fluid, or mercury or green color concentrate to provide positive, negative, and differential pressure measurement for determining velocity and static pressures, leakage, fan and blower efficiency, filter resistance, and gas pressures. The columns are composed of 1/8" outside diameter flexible and shatterproof clear butyrate tubing for use with colored water, red fluid, or mercury (sold separately).
