Dwyer Instruments 1223-20-W/M | U-tube manometer | Range 10-0-10" w.c.
Dwyer® Flex-Tube® U-Tube Manometers combine the robust, long-lasting plastic construction with the inherent precision of the straightforward "U" Tube. Positive, negative, and differential pressures are all measured by these affordable manometers. The flexible, shatter-proof,.375" O.D. transparent butyrate tubing used in the columns is clear. For cleaning, they are easily accessible. White scale channel surrounds the indicator tube to maximize color contrast. High impact polystyrene plastic is extruded to make scales, which are designed to retain columns precisely aligned. For optimal legibility, numbers and graduations on stark white scales are silkscreened in black.
