Measurement Method

The HEM-8721 and HEM-7120 are fully automatic. That means the whole measurement procedure can be conducted with a single button.

Hypertension Indicator

Sometimes, you may miss out on the seriousness of the result. So, this hypertension indicator notifies you in case your systolic or diastolic pressure exceeds the standard healthy range.

Irregular Heartbeat Indicator

It indicates the user to retake the measurement in case of body movement detection during the analysis. This feature is available in both HEM-8721 and HEM-7120 BP monitors.

IntelliSense Technology

Omron uses innovative IntelliSense Technology to design its BP monitors, which give more accurate results.

With the method, there is no need for the users to select the inflation level manually. It causes the arm cuff to inflate and deflate at the optimum level for every user.

This technology is especially necessary for users with hypertension, arrhythmia, or heart disorder, as their pressure level is likely to fluctuate.
Both the model – HEM-8721 and HEM-7120 have InetlliSense Technology installed in it.


Both the BP monitors – HEM-8721 and HEM-7120 – excels in terms of readability. Each of them has an LCD screen with a physical dimension of 59 mm x 43 mm. The monitors have the measurement name viz “SYS”, “DIA”, and “PULSE” labelled beside the display section. It prevents the misreading of the result.

Moreover, the monitors display the result in an extra-large icon so that even the older adults can read it conveniently.

Reading Storage

Both the BP monitors can store the last reading. But sometimes, it becomes necessary to keep more than one result for better analysis. However, doing this job manually can be inconvenient.

User Friendliness

For achieving precise reading, the proper placement of the arm cuff is mandatory. To guide the user through the process, the manufacturers have diagrammatically described each step on the arm cuff material. Both the models’ arm cuffs have this feature.
