High definition retina full touch color screen with a resolution of 360*360, wider color gamut and clearer picture quality Innovative design of lead ECG glass, using nano ECG glass on the back and stainless steel electrode on the right, ECG circulates in the body and heart, resulting in ECG wave reports Bluetooth calls can be made anytime, anywhere through the watch, freeing up hands and making life more convenient The 60s micro physical examination function allows users to detect health indicators based on their watches and participate in professional health research projects within 60 seconds. Users can obtain physiological parameters such as heart rate, blood pressure, blood oxygen, pressure and body temperature. And provide relevant guidance and suggestions based on health research conducted by professional institutions Multiple electrocardiogram disease screening, heart health index risk assessment of arrhythmia, HRV data detection, reports can be viewed on the APP, providing a comprehensive understanding of heart health and helping you maintain it Measuring body fat to know the distribution rate of body fat and bone provides a more comprehensive understanding of the health status of the body. It is important to constantly remind people to engage in effective and targeted health exercises Easily record physiological cycles, provide thoughtful tips and avoid awkward periods 24-hour continuous dynamic heart rate monitoring (with live detection function), combined with intelligent heart rate algorithms,can accurately monitor both resting heart rate and dynamic heart rate. Through scientifically quantified big data, daily heart rate curve changes can be seen Specifications: Hardware information Product model TK28 Product size 41*49.0*11MM CPU Realtek 8762D+AC6963A Gravity sensor ST8321 ECG chip GH 3228 (high-precision electrocardiogram HRV) Heart rate and blood oxygen chip OSRAM: SFH2703 BT Bluetooth LE 5.1 LCD 1.27 inch high-resolution 360*360 TFT full touch screen TP Full screen touch control, mobile app control Motor Support Charging mode magnetic charging Waterproof IP68 waterproof Battery capacity 280mAh high-density polymer lithium battery Software function Function Overview 1.
