Closer Look at the Features of E400 Smartwatch
Let’s explore the key features of the E400 Smartwatch:
- Non-Invasive Glucose Measurements: One of the standout features of this smartwatch is its ability to measure blood glucose levels non-invasively. The technology behind this measurement is intriguing, with speculation that it analyses sweat or perspiration between two electrodes on the device.
- Health Monitoring: The E400 offers a range of health monitoring features, including EKG (Electrocardiogram), ECG (Electrocardiography), and SpO2 (Blood Oxygen Saturation) monitoring. These features provide valuable insights into your heart health and oxygen levels.
- Continuous Heart Rate Tracking: The smartwatch offers continuous heart rate tracking, which can help you monitor your heart’s performance during various activities and at rest.
- Body Temperature Measurement: Another notable feature is the ability to measure body temperature. The smartwatch calculates skin temperature and relates it to body temperature, making it a useful tool for detecting fever or changes in temperature.
- Blood Pressure Monitoring: The E400 includes blood pressure monitoring capabilities. This feature provides data on your blood pressure trends, offering insights into your cardiovascular health.
- Fitness and Sleep Tracking: The watch tracks your daily activities, including step count, calorie burn, and sleep patterns. This data can be invaluable for assessing your overall health and making informed lifestyle choices.
- Smartwatch Capabilities: Beyond health monitoring, the E400 functions as a standard smartwatch. It can display notifications from your paired smartphone, allowing you to stay connected even while on the move.
- User-Friendly App: The smartwatch pairs with the “hband” app, where you can view and analyse the collected health data. The app provides detailed insights into your heart rate, blood pressure, blood glucose, and other vital statistics.
