Rossmax BQ705 Wrist Blood Pressure Monitor is more convenient and portable. Rossmax BQ705 Wrist Blood Pressure Monitor provides measurements equivalent to those obtained by a trained observer using cuff/stethoscope auscultation method, within the limits prescribed by the American National Standard, Electronic or Automated Sphygmomanometers. Rossmax CH155F Automatic Blood Pressure Monitor uses the oscillometric method to detect your blood pressure. The "Movement Detection" helps reminding the user to remain still and is indicating any body movement during measurement. The specified icon appears once a "body movement" has been detected during and after each measurement. This unit is equipped with innovative blood pressure risk indicator, which visually indicates the assumed risk level (normal/prehypertension/stage 1 hypertension/stage 2 hypertension) of the result after each measurement. This unit is equipped with an Irregular Heartbeat (IHB) Detection which allows those who have an irregular heartbeat to obtain accurate measurements alerting the user of the presence of an irregular heartbeat during the measurement. This device incorporates smart sense technology which gives more precise readings with greater accuracy. Smart Sense Technology utilizes an advanced air control system. The electronic deflation valve precisely controls the deflation rate and allows the monitor to detect and analyze pulse signals, adjusting cuff pressure during deflation. This significantly ensures more precise analysis, while reaching greater accuracy.
