Medical-grade precision measurement, data comparable to hospital equipment Adopting the measurement principle of oscillometric method with imported high-precision pressure sensor, the error is 3mmHg, 2mmHg, in line with ESH certification standards, the measurement results can be directly used as a reference for health management. Dual calibration technology: supports manual calibration and automatic optimisation by intelligent algorithm, the data is always reliable for long-term use. Intelligent operation, suitable for the whole family One-key foolproof operation: large round measurement buttons, boot that is measured, no need for complex settings, the elderly independent operation without pressure. Voice announcement + large screen display: high-definition LED backlit screen, automatic synchronous voice reading values, night measurement is not blinding, poor eyesight can also be clearly viewed. Dual-user memory storage: can store 299 groups of measurement data, automatically match the user number, accurately record personal blood pressure trends, support one-key query historical data. Innovative Functions Irregular pulse detection: real-time monitoring of heartbeat rhythm, and immediate drip drip alarm when abnormalities are detected, providing early warning of potential risks such as atrial fibrillation and premature beats. Blood Pressure Classification Alert: According to the World Health Organisation standards, the measurement results are automatically labelled as normal, high and low, which is intuitive and easy to understand. Intelligent pressurisation technology: automatic identification of vascular resistance, dynamic adjustment of inflation pressure, reducing measurement discomfort, cuff wear error reminder function to avoid human error. Portable design, health measurement anytime, anywhere Lightweight body: the main body weighs only about 200g, with a foldable cuff, into the carry-on bag can travel, business trips, travelling without forgetting to monitor. Long-life lithium battery: Built-in 1200mAh rechargeable battery, can be fully charged for about 150 measurements, Type-C interface is compatible with mobile phone chargers, say goodbye to the trouble of frequent battery replacement.
