Better health through artificial intelligence
Kardena CARE Pro 2 smartwatch is built with the latest multioximeter sensor SFH2201, offering a 14% larger spectral range compared to the SFH2703, in combination with seven-fold Fresnel lenses, which ensures unprecedented precision. This technology was also developed by the German company OSRAM at their Regensburg site. The sensors use up to 750-nanometer light wavelengths to analyse blood flow in the topmost millimetres of the wrist skin.
The sensor technology with a high accuracy of 512 Hertz, used here for the first time, comes from the US-based Maxim Integrated Products Inc. from California. It analyses the diagram for various anomalies. Another innovation of the Kardena CARE Pro 2 smartwatch is the improved sleep monitoring, including REM phase analysis with an alarm function for sleep apnea attacks, a heart rate variability analysis including a Lorenz plot display for early disease detection, such as an overactive thyroid, or for monitoring the menstrual cycle.

A smartwatch for blood pressure measurement & heart rate

Technical data – Innovations and unique functions
✅ The motto of the Kardena CARE Pro 2 health watch is: more health with artificial intelligence. This is provided by the "Max86176" from Maxim Integrated, based in the US state of California. It offers three electrodes with a total of 512 Hertz sampling frequency – even for the finest recordings at the highest level.
✅ The app diagram is examined for 13 anomalies using artificial intelligence and offers almost optimal preparation for the next conversation with your cardiologist. The diagram is forwarded directly to them at the push of a button, via email or WhatsApp.
✅ The watch shows you the measurement values just taken. We recommend using our new app to get a better overview of your health. In the app, you will find an overview of all measurements, a static evaluation, various diagrams, and statistics. Transferring the values to the doctor is also possible via the app. Use this function to provide your family doctor or cardiologist with as much information as possible. Your doctor can then create an optimal therapy/treatment plan for you.
✅ In the new Kardena CARE Pro 2, the sensors are double-integrated. For you, this means: double precision. The watch now has six light sources and 7 OSRAM Fresnel lenses for light bundling.
✅ Incredible sharpness thanks to 57,600 pixels in the IPS display: our Pro guarantees, figuratively speaking, a razor-sharp image with the highest level of visibility - even in strong sunlight on the display.

Kardena – innovative technology for a better life.
The new CARE Pro 2 combines its artificial intelligence with multiple pulse oximetry sensors from OSRAM and sensor technology from Maxim Integrated. In contrast to conventional trackers, the results are significantly more precise due to the calibration. Furthermore, unique features await you – e.g., sleep apnea analysis, calibratable continuous blood pressure monitoring, measurements with artificial intelligence, blood oxygen control, HRV analysis, or REM phase sleep analysis.
