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). The manometer is calibrated in inH2O or mmH2O using water and is available in W/M-style for use with fluorescein green concentrate or mercury (sold separately), or D-style for use with red gauge fluid. The water column has 1/10" divisions for inch scales or 2mm for metric units. Units are silkscreened in black on a white background to ease reading. The manometer has magnetic clips to mount on vertical surfaces and a clamp bar to prevent slipping. Magnets are removable to customize mounting. The manometer includes a bottle of fluorescein green or red gauge fluid.SpecificationsWhat's in the Box?
