Are you looking for an oximeter that does more than simply measuring data? That's possible. The Beurer PO80 accurately measures the amount of oxygen (SpO2) in your blood and your heart rate frequency. This isn't the only function that distinguishes the PO80 from its siblings. It can also measure for 24 consecutive hours. This offers the possibility to track the SpO2 and heart rate frequency over a longer period of time. On top of that, you can connect the PO80 to the computer with the USB cable and view and analyze all measurements with the Beurer software.
