The Graham Field-203 is a specialized aneroid sphygmomanometer designed for high-performance medical environments. It features a luminescent dial that absorbs light to provide clear visibility in dim or low-light clinical settings. To ensure longevity, the manometer is encased in a protective rubber gauge guard that helps absorb impact and prevent calibration shifts if the device is dropped. This unit includes a high-quality black Accumax nylon cuff with index and range markings for accurate sizing. The set is entirely latex-free and comes with a deluxe inflation bulb, a precision air release valve, and a zippered carrying case for secure transport.
