That’s why we manufacture quality components and assemble our Riester Sphygmomanometers in Germany. The precision and product longevity of Riester’s sphygmomanometers have been proven by test results. Riester’s „shock-proof“ is a patented technology. Riester aneroid sphygmomanometers differ not only in precision, comparable to Mercury devices, but also from a nearly unlimited lifetime. Maximum Riester sphygmomanometer error tolerance is +/- 2mm Hg, which surpasses international standards. Further proof of its unparalleled quality is the diaphragm pressure-loading capacity of up to 600 mm Hg. Choose from our large product range with screw- or plug-in connections and a large variety of cuffs. Riester sphygmomanometers are available latex-free, with high precision air release valves and micro filters to protect the measuring system. Riester aneroid sphygmomanometers come with a 2 year warranty (5 year warranty on R1 shock-proof calibration).
