MDF® Mobile Aneroid Sphygmomanometer - Professional Blood Pressure Monitor The MDF® Mobile Aneroid Sphygmomanometer incorporates all the features of the MDF® Desk and Wall Aneroid Sphygmomanometer on a quiet, sturdy, easy-to-roll stand. Perfectly suited for vicinities in hospitals, clinics, and nursing homes where repeated blood pressure measurements are conducted. Stress-tested over 3,000 times and calibrated 5 times, it is one of the most durable, accurate, and dependable blood pressure measurement devices on the market. To reduce the parallax effect, the large scale (15 cm) is imprinted with black-bold dials and pressed with a raised outer rim to achieve accurate viewing at all angles. Doubly protected against shock, the internal manometer is enclosed in a die-cast zinc housing that is cushioned within the external high-impact thermoplastic case. The faceplate can swivel smoothly with a wide range of 180° horizontally and 90° vertically to ensure the gauge is easy to see.
