The precision and product longevity of Certeza's sphygmomanometers have been proven by test results. Certeza's shock-proof is a patented technology. Sphygmomanometers differ not only in precision, comparable to Mercury devices, but also from a nearly unlimited lifetime. Certeza's 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. Certeza's sphygmomanometers are available in latex-free, with high precision air release valves and micro filters to protect the measuring system. Certeza's aneroid sphygmomanometers come with a 2 year warranty.
