Compared to a home blood pressure monitor, a professional blood pressure monitor has a larger capacity for repeated readings. The device is a battery (rechargeable)-operated and allows 300 measurements with a single charge. In addition, it has an ergonomic design that makes handling easy and is shockproof. Both the pressure and the device's operation are programmable using the oscillometric method. There are two arm cuffs in the sizes medium and large included with HBP 1320.
