Without sacrificing the accuracy, which is ensured by sharing the measurement algorithm and “M” cuff used with our preceding QM*2 holding blood pressure monitor WS-820, WSK provides you more measurement comfort by FUZZY inflation. Oscillometric blood pressure monitors determine blood pressure with oscillations which occur from inflating and deflating a cuff wrapped over measurement site. Regular blood pressure monitors inflate the cuff to a certain point regardless of blood pressure values, but WSK inflates the cuff to the value just enough to take your blood pressure. • Oscillometric method-touch sensor operation • 15 digits LCD display – Large with WHO classifications • 60 x 2 memory bank + average • Detects Arrhythmia and show pulse pressure display • Clinically proven for accuracy NOTE: ALL OUR ITEMS ARE BRAND NEW IN PACKAGING.
