A sphygmomanometer of the aneroid gauge type having bellows connected through gears to rotate a shaft, and a pointer mounted on the shaft and movable over a dial to indicate pressure, includes recording means manually actuable to temporarily mark the systolic and diastolic pressures. The recording means has a two layer adhesion marking means attached to the dial and a stylus carried by the shaft in registry with the pointer, and movable to impress a mark upon the adhesion marking means. A separator is provided to detach the two layers to erase the earlier marks when the sphygmomanometer is again used.
