Aneroid Sphygmomanometer is one in the Lumiscope Lifetime Calibration Warranty series. This is the last of the ones with latex bladders and the price reflects it - but the bladder is INSIDE the cuff, so it shouldn't be a problem. New units will be $21.95 with non-latex bladders. Standard air release valve, Zippered carrying case and no pin-stop at zero for accuracy. Calibrated nylon cuff in blue, blue Velcro closure. This cuff is larger in all dimensions [ 7" by 26" cuff ] to allow accurate blood pressures on larger arms and highly muscled arms.
