M-300A Digital Blood Pressure Monitor will make recording your blood pressure measurements simple
Taking your blood pressure shouldn’t be stressful. The Dr. Frei M-300A Digital Blood Pressure Monitor is a fully automatic, digital blood-pressure measuring device for use on the upper arm. It enables very fast and reliable measurement of the systolic and diastolic blood-pressure as well as the pulse frequency by way of the oscillometric method of measuring.
Blood pressure is a measure of the force that your heart uses to pump blood around your body. Blood pressure is measured in millimetres of mercury (mmHg). The readings are given as two numbers or levels. The systolic reading is first – the level of pressure when your heart pumps blood through your arteries and around your body. Followed by the diastolic reading - the level of pressure when your heart is resting before it pumps again.
Definitions and Classification of blood pressure levels according to 2007 ESH-ESC Practice Guidelines for the Management of Arterial Hypertension: Data in mmHg.


Digital blood pressure monitor with a range of features to keep your blood pressure in check
Positioned on the left side of the display you will find the blood pressure indicator. After the measurement a colour will appear in the bars on the left part of the display. Green signifies optimal blood pressure. Yellow signifies elevated and orange indicates it’s too high. Red indicates its dangerously high. This function helps you to self-evaluate.
Irregular heart beat detection
Your Dr. Frei M-300A Digital Blood Pressure Monitor indicates an allorhythmic heartbeat. If the symbol of IHB Advanced appears on the display, it’s indicating that abnormality in heartbeat frequency was detected during the measurement. In this case, the result may deviate from your normal blood pressure - repeat the measurement.
The Dr. Frei M-300A Digital Blood Pressure Monitor is designed to help you stay aware of your blood pressure. Always seek professional medical advice for a diagnosis.
