Based on oscillometric methodology and silicon integrated pressure sensor, blood pressure and pulse rate can be measured automatically and non-invasively. Reliable and accurate blood pressure and heart rate parameters are obtained within a short period.The voice function enables the device to communicate results of blood pressure and heart parameters to the user instantlyThe presence of large cuff circumference (22cm-48cm) makes it suitable all size of armsThe most sixty (60) recent measurements can be stored in the monitor. USES Ando Automated Electronic Blood Pressure Monitor is for use by medical professionals or at home and is a non-invasive blood pressure measurement system intended to measure the diastolic and systolic blood pressures and pulse rate of an adult individual by using a non- invasive technique in which an inflatable cuff is wrapped around the arm. SPECIFICATION Model: KD-595, Machine size:153 mm x108mmx60mm,Cuff circumference (22cm-48cm), Memory volume: 60 times with time and date stamp, Power source: DC: 6V----600Ma,Batteries 4x1.5V SIZE AA, battery life: approximately 2 months with alkaline batteries and 3-min.usage per day, Range of cuff pressure :0-300mmHg,Range of measurement : 30-280mmHg, Pressure accuracy ± 3mmHg, Pulse rate range:40-180/min, accuracy: ± 5% A PACK Contains blood pressure monitor, arm cuff, operation guide, soft storage case and four (4) AA batteries. 10packs/carton NOTICE Stay quiet, calm and rest for 5 minutes before blood pressure measurement. Relex at least 1 or 1.5 minutes between measurements to allow the blood circulation in your arm to recover. Blood pressure measurements determined by the monitor are equivalent to those obtained by a trained observer using the cuff/stethoscope auscultation method, within the limits prescribed by the American National Standard Institute,
