CardioTech products offer clinically proven technology and are used by physicians and hospitals around the world. Compact, portable and simple-to-use, the Ozeri CardioTech Blood Pressure Monitor is an advanced wrist cuff monitor with MWI (Measure While Inflate) technology that automatically inflates to the appropriate level (no adjustments required) while reducing measurement time while offering greater accuracy. This advanced capability adds convenience and ease of use to those with conditions (such as arrhythmia) that lead to fluctuating blood pressure. The Ozeri CardioTech Premium Series Digital Blood Pressure Monitor stores up to 1197 blood pressure readings with date and time Memory recall (399 readings x 3 users), and automatically classifies each blood pressure reading according to World Health Organization hypertension guidelines with a new Color Alert LCD that color codes the systolic and diastolic readings according to green (normal), orange (prehypertension) and red (hypertension) levels. It also calculates average blood pressure readings based on the 3 most recent readings, and detects irregular heart (Arrhythmia) for an improved understanding of your heart's heath. Based on a wrist cuff design, the Ozeri CardioTech Blood Pressure Monitor is especially helpful for users with above average arm sizes and it stores compactly in a carrying case for travel. Backed by a 5 year warranty, the Ozeri CardioTech Blood Pressure Monitor ships with 2 AAA batteries included, a carrying case and user manual.
