The Aneroid Sphygmomanometer/Dual Head Kit (model A3) includes the same features as the best-selling A2 kit except that it benefits from having a traditional dual head stethoscope. This stethoscope has a chestpiece made from lightweight aluminum which has an inlaid non-chill ring. It is a superior stethoscope for general auscultation. The Aneroid Sphygmomanometer/Dual Head Kit is latex-free and has a nylon cuff with a cuff range of 10" to 16". It features index and range markings with an artery indicator mark, an owner ID label, a gauge holder, an air release valve and a standard inflation bulb. It is supplied with a 6" x 9" color-matched nylon carry case.
