Simply more secure. Double the security in blood pressure measurement.

The innovative Duo Sensor Technology combines two professional measuring technologies: the oscillometric technology and the Korotkoff's technology. Whilst most automatic blood pressure self-measurement devices only use oscillometric technology, Duo Sensor Technology primarily utilises Korotkoff's highly accurate method of blood pressure measurement. Only in exceptional cases will the device display the results obtained by oscillometric technology. This device ensures high accuracy and excellent handling comfort.

The advantages at a glance

• Reliable blood pressure and pulse measurement results
• Particularly suitable for people with high blood pressure and various types of heart rhythm disorders
• Easy to use
• Comfortable measurement
• Batteries for 1,300 measurings included
• Extend 3 year warranty.

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. Duo Sensor Technology utilises this accuracy which makes is particularly suitable for people who want accurate measurement results.

These may be important for people who receive drug treatment due to high blood pressure in helping their doctor prescribe the right dosage of the drug for them. Moreover, many patients with certain types of disordered heart rhythms can now obtain accurate values when using this automatic blood pressure measuring device. Also, the microphone is mounted in the device itself rather than the cuff, reducing susceptibility to malfunction from operating errors. Duo Sensor Technology thus produces accurate results and is still easy to use.

... and the special characteristics of the oscillometric measurement

The oscillometric measurement detects the pulse wave vibrations in the artery rather than pulse sounds. Using a pre-programmed formula known as algorithm, a processor calculates the most likely blood pressure values. The measurement results are calculated indirectly, whereas the Korotkoff method measures blood pressure directly on the artery. The oscillometric measurement method is considered less accurate than the Korotkoff method. However, it is suitable for people whose pulse sounds are so faint that they cannot be auscultated by Korotkoff's method.
