OMRON HEM 7120 BP Monitor Review

OMRON’s HEM-7120 Fully Automatic Digital Blood Pressure Monitor is a fully automatic upper arm blood pressure monitoring system, operating on oscillometric principle. It measures not only your blood pressure but also the pulse rate. By using the advanced Intellisense Technology, this product comfortably controls the cuff inflation and it also doesn’t need to set pressure pre-setting or re-inflation.

The best thing of this product is that even a slight movement can show a change in pressure, which results in the most accurate measurement.

This product also detects irregular heartbeat along with blood pressure and as it is featured with body movement indicator and hypertension indicator, it helps you keep an eye on cardiovascular health.

Top Features

Omron HEM-7120 BP monitoring machine, is one of the best OMRON has ever produced and customers do agree with it. Here are some of the top features that makes it a highly demanding BP model –

Size & Portability

The dimension of this BP machine is 12*12*16 cm and has a weight of about 250 gm without the batteries. Regardless of the Intellisense Technology chip, the designer has given it a sleek design, which is very handy to use and also portable and easy to carry.


Accuracy is one of the most concerning things and has to be when it comes to health issues. In most machines, blood pressure readings may be inaccurate in 5% to 15% of the cases, but talking about HEM-7120, the error rate is less by some extent as compared to the other machines. Apart from this, if an irregular heartbeat symbol flashes on the display while measuring the blood pressure, it indicates that the blood pressure is out of the recommended range (<299 mmHg). It’s better to consult a doctor immediately if the blood pressure is above the recommended range and showing an error.

Monitor or Display

Omron 7120 BP machine

The OMRON HEM-7120 BP machine shows you diastolic BP, systolic BP and also pulse rate as shown in the figure. By just tapping the Start/Stop switch, you can get the results. The monitor has a dimension of 103(w) mm * 80(h) mm * 129 (l) mm with liquid Crystal Display (LCD). The reading numbers are large enough to read easily.

Arm Cuff

Arm cuff of HEM 7120 is made of nylon and polyester which makes it more comfortable while using and the air tube is of polyvinyl chloride. The arm cuff has a dimension of about 22-32 cm approximately. The size of the arm cuff is very important as the reading mainly depends on this. So you must note the size of the arm cuff before ordering it so that it fits in properly in your arm. The device is based on the Intellisense technology which is embedded on the chip present inside the machine and makes the cuff inflation more comfortable.

Air Jack & AC Adapter Jack

For accurate measurements, the air plug needs to put inside the air jack very carefully. You need to purchase the AC adaptor separately having an output voltage of DC 6V and current of 900 mA.


Different websites have slightly different price tags. In my opinion, you can go with Amazon, as its price is comparatively less as compraed to others.

Battery Life

The machine runs on 4 AA batteries and can measure up to 1000 measurements approximately. It can also run on an AC adapter which has to be bought separately.

Brand Value
