A blood pressure meter, or sphygmomanometer, is a device that is used to measure blood pressure. The meter is used with an inflatable cuff for restricting blood flow and a pump to inflate the cuff. Digital blood pressure meters typically measure both systolic and diastolic pressures by an oscillometric detection method, using a piezoelectric pressure sensor.

A digital blood pressure meter allows easy monitoring of blood pressure at home, in a doctor’s office or in a hospital. Today’s blood pressure meters must meet the demands of measuring, storing and transmitting blood pressure, pulse and other medical data. To meet these demands, we offer a broad portfolio of hardware, software and development tools to build your product as well as demonstration design files to speed up your design’s time to market.
