The Duo Sensor Technology is described as the innovative combination of two professional measuring technologies. Whilst most automatic blood pressure self-measurement devices only use oscillometric technology, Duo Sensor Technology combines the advantages of both technologies. During the measurement procedure, Duo Sensor Technology primarily utilises Korotkoff's highly accurate method of blood pressure measurement.

The high accuracy of blood pressure measurement using Korotkoff's method...

Korotkoff's principle of blood pressure measurement is characterised by its high accuracy and reduced susceptibility to malfunction, producing correct measured values even in patients with a variety of heart rhythm disorders. This is why doctors normally use a stethoscope to listen for what are known as Korotkoff sounds in order to measure blood pressure.
