The small, compact design of the HEM-609 Wrist Blood Pressure monitor makes taking blood pressure easy to do almost anywhere. It's watch-like styling means you no longer have to take off your shirt or struggle to roll your sleeves up past your elbow to get a blood pressure reading. The HEM-609 Wrist Blood Pressure Monitor is completely automatic - just touch one button and it will automatically inflate, quickly and accurately get your blood pressure and pulse rate and then automatically deflate, too! And a memory records your last 14 measurements for you, making keeping track of your history simple. It operates on just 2 'AA' batteries, which are included for you. The HEM-609 even comes with a deluxe protective case. "Intellisense" technology used by the 609 Blood Pressure Monitor means that it inflates the cuff to the ideal level with each use. The sensors quickly stop the cuff's inflation to keep it comfortable - no matter what size your wrist is. No adjustments are required by the user to select an inflation level. This is especially important for hypertensive users and for people with certain arrhythmia or heart disorder, because their blood pressure is likely to fluctuate. The advantage is Personalized Inflation for maximum comfort. This may be one of the most comfortable and accurate blood pressure readings you will ever have!
