What mobile medical devices can detect health at home?

Many people have smart bracelets and body fat scales at home to see their health. However, many of these products have not passed the CFDA medical device certification, and the test results still have great errors. If you really want to detect physical indicators more accurately, I recommend mobile medical equipment with CFDA certification, such as the multifunctional health detector of Lingtuo Technology, which is small and portable and can detect six functions such as body temperature, blood pressure and ECG.
