This device complies with IEC 80601-2-30, and has been clinically tested in accordance with ISO 81060-
2:2018 and AMD1:2020. The clinical trial included a resting blood pressure monitoring test and an
ambulatory blood pressure monitoring test. The resting blood pressure monitoring test was conducted on
more than 85 subjects. The average deviation of their systolic and diastolic blood pressures did not exceed
±5 mmHg, and the standard deviation of their systolic and diastolic blood pressures did not exceed 8 mmHg.
The ambulatory blood pressure monitoring test was conducted on more than 35 subjects. The average
deviation of their systolic and diastolic blood pressures did not exceed ±5 mmHg, and the standard deviation
of their systolic and diastolic blood pressures did not exceed 8 mmHg, in this instance either.
Oscillometric method
0 mmHg ~ 300 mmHg (0 kPa ~ 40 kPa)
40 times/min ~ 180 times/min
Pressure: ±3 mmHg (±0.4 kPa)
Pulse rate: ±5%
Diastolic blood pressure: 40 mmHg ~ 130 mmHg (5.3 kPa ~ 17.3 kPa)
Systolic blood pressure: 60 mmHg ~ 230 mmHg (8.0 kPa ~ 30.7 kPa)
Automatic pressure pump
Automatic fast deflation
Single blood pressure measurement time < 180 seconds
M-sized airbag: 13.0 cm ~ 16.0 cm
L-sized airbag: 16.1 cm ~ 21.0 cm
Please select the appropriate airbag for your wrist circumference. If your
wrist circumference exceeds 21.0 cm, the accuracy of blood pressure
measurements may be affected.
