Wrist blood pressure monitor, 90 memory, thin, soft cuff type, CHWM541, 1 unit

It stores 90 sets of systolic blood pressure, diastolic blood pressure and pulse rate. Press the memory button to display the average value of the last three readings. If your hand, wrist, etc. moves during measurement and a large change in pressure is detected, a "body movement mark" will appear to notify you after the measurement is completed. If the pulse interval during measurement is irregular, a "pulse interval variation mark" will be displayed to notify you after the measurement is completed. The device is about 15mm thin, making it easy to carry around.
