Dwyer Flex-Tube U-Tube Manometers
Cost-effective u-tube manometers that measure positive, negative, and differential pressures. For use in duct static pressure, calibration labs, and filter monitoring applications.
Dwyer Flex-Tube U-tube manometers combine the U-Tube's inherent accuracy with the durability of tough, long-lasting plastic construction.
Easy-to-clean columns are of 0.375" O.D. flexible and shatterproof clear butyrate tubing. The indicating tube is backed by a white scale channel for maximum color contrast. Stark white scales are extruded high-impact polystyrene plastic with graduations and numbers silkscreen-printed in black for maximum legibility.
All Flex-Tubes are suitable for total pressures to 100 PSI, and great for determining velocity and static pressures, leakage, fan and blower efficiency, filter resistance, and gas pressures.
- Series 1221 is the most affordable basic U-gage. Includes one pair of carrying plugs and a pair of non-kink vinyl tube connectors.
- Series 1222 offers all the features of the 1221 plus magnetic clips for mounting to any vertical steel surface, and a clamp bar to ensure against U-tube slipping.
- Series 1223 manometer U-gage is great for either portable or stationary use. Tubing is permanently bonded to a molded, high impact acrylic plastic top that contains safety traps to prevent loss of indicating fluid in case of accidental over-pressure. Large magnetic clips and clamp bar are provided. Standard type A connections include two rapid shut-off type molded nylon tubing connections, two 3-foot lengths of flexible Tygon plastic tubing, and two 1/8" pipe thread to tube adapters.
