Dwyer Instruments 1221-12-W/M Manometer 320734-701 Why is the Sandhog designThe Dwyer Instruments 1221 12 W M Manometer is a field proven Flex Tube U Tube Manometer designed for the high precision pressure diagnostics required in heavy duty HVACR environments. This differential pressure gauge features a 12 inch water column range (6 0 6" w. c.), making it ideal for determining duct static pressure, filter resistance, and fan efficiency. Constructed with 0. 375" O. D. clear butyrate tubing, the columns are specifically
