Abstract: Disclosed herein is an improved manometer in which the calibrated scale for reading the fluid pressure is provided on a transparent sheath rather than directly on the manometer tube, the sheath being slidably mounted on the manometer tube. This sheathing permits the zero point of the scale to be readily adjusted and includes a cylindrical portion integral with a wing, the wing carrying the scale either as a direct imprint or as an insert in the wing. An indicator for marking the meniscus level encapsulates the sheathing. The indicator is slidable on the sheathing and has a mark for establishing the pressure reading for subsequent reference.
