Dwyer Instruments 1221-12-D | U-tube manometer | Range 6-0-6" 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 columns are made of flexible, shatter-proof,.375" O.D. transparent butyrate tubing. For cleaning, they are easily accessible. For optimal color contrast, a white scale channel surrounds the indicating tube. The extruded high-impact polystyrene plastic used in scales is designed to retain columns precisely aligned. For optimal legibility, numbers and graduations on stark white scales are silkscreened in black.
