Dwyer Series 1221/1222/1223 is inexpensive manometers measure positive, negative, and differential pressures. Dwyer Flex-Tube® U-Tube Manometers combine the inherent accuracy of the simple “U” Tube with the durability of tough, long-lasting plastic construction. Columns are of .375″ O.D. flexible and shatterproof clear butyrate tubing. They are easily accessible for cleaning. The indicating tube is backed by a white scale channel to provide maximum color contrast. Scales are extruded high-impact polystyrene plastic, formed to hold columns in perfect alignment. Stark white scales have graduations and numbers silkscreen-printed in black for maximum legibility.
Numerous models selection and features including over-pressure safety traps, in full scale ranges from 8″ to 36″ of water or mercury. All are suitable for total pressures to 100 psi – for determining velocity and static pressures, leakage, fan and blower efficiency, filter resistance, and gas pressures. Ideal wherever a portable, direct reading manometer is needed. Standard ranges and markings as shown or special ranges, colors, logos, and brand names for OEM quantity orders are available.
