SIMPLE AND PAINLESS: The pulse oximeter measures your oxygen saturation (SpO2) and your heart rate (pulse rate) - Clinically validated accuracy for home use HEALTH MONITORING: The pulse oximeter is suitable for checking and regularly monitoring oxygen saturation - respiratory diseases such as asthma, COPD, and other lung diseases can lead to a drop in oxygen saturation. SMALL AND HANDY: Thanks to its compact size, the pulse oximeter can be stored in any pocket and is therefore also suitable for on the go, e.g., when hiking or traveling. COLOR DISPLAY: Your measured values are clearly displayed on the easy-to-read color display with a total of 4 display formats. ACCESSORIES: The oximeter comes with a carrying strap and a fanny pack. Pulse Oxygen Saturation and Heart Rate Measurement Pulse measurement is used to assess pulse oxygen saturation (SpO2). This is the percentage of hemoglobin molecules that have bound oxygen in the blood. In healthy people, pulse oxygen saturation is between 94% and 98%. The measurement also allows you to determine your heart rate. Easy to use: Small and practical The perfect self-monitoring device for home and travel. With the pulse oximeter, you can optimally monitor your arterial pulse oxygen saturation (SpO2) and heart rate (pulse). Display with 6 perspectives The particularly easy-to-read color display offers 4 perspectives and 2 displays. You can adjust the screen brightness. Displayed/Measured Value The device displays pulse oxygen saturation (SpO2), heart rate, pulse bar, and pulse waveform.
