Dynarex Blood Pressure Kits include a single or dual-head stethoscope and an adult sphygmomanometer. The stethoscope is sleek, durable, and lightweight with a non-chill, anodized chest piece. It features 22″ latex-free PVC tubing with an adjustable binaural. The 300mmHg sphygmomanometer is chrome-plated, easy to read and has an air-release valve. The stethoscopes, single or dual, are available separately, as are the sphygmomanometers in a range of cuff sizes.
