Dwyer Instruments 1221-16-D | U-tube manometer | Range 8-0-8" w.c.
The inherent precision of a straightforward "U" tube combined with the robustness of an all-plastic construction make up Dwyer® Flex-Tube® U-Tube Manometers. These low-cost manometers detect differential, positive, and negative pressures. The flexible, break-proof,.375" O.D. transparent butyrate tubing used in the columns is clear. Cleaning them is simple and easy. To achieve the highest possible color contrast, a white scale channel surrounds the indicating tube. To maintain exact alignment of columns, scales are made of extruded high-impact polystyrene plastic. For optimal visibility, black silkscreen printing is used for the graduations and digits on stark white scales.
