Welch Allyn DuraShock Integrated Aneroid Sphygmomanometers. Made without gears, these sphygmomanometers meet or exceed AAMI SP9 specifications for shock-resistance and maintain its performance characteristics after a 30" drop onto a hard surface. The gauge and cuff design allow for an extremely low profile and more convenient readings, handling and storage. The gauge snaps directly into the cuff for fast, easy cuff changes and rotates 360° for easy viewing. The cuff is designed for accurate application to the brachial artery of either arm for more convenient measurements. It is also faster and easier to orient and apply, especially in low-light conditions. The one-piece cuff is durable and latex-free, so it is easy to clean, disinfect or sterilize. The cuff comes standard in two-tone gray; Cuff WADS45-09P and Cuff WADS4509PC come in color print. Choose from sphygmomanometers with or without polyester zipper cases.
