Omron 3 Series Upper Arm Blood Pressure Monitor Review

The Omron 3 Series BP710N model is an upgraded version of the original BP710 device. As with all Omron upper arm blood pressure monitors, the cuff will fit an arm circumference from 7″ to 19″.

Additional features include one-touch operation, a 14-reading memory, and clear systolic and diastolic readings via the large display screen.

But how does their most affordable upper arm blood pressure monitor compare to devices like the Omron 7 Series or 10 Series?

In our review, we’ll take a close look at the design features, ease of use, accuracy, and customer feedback. This is to determine whether the Omron 3 Series is the best home blood pressure monitor for you.

Design Features

The Omron Series 3 BP710 includes the blood pressure monitor, cuff, and instruction manual

As with their wrist BPMs, the Omron BP710N uses the oscillometric method of blood pressure measurement.

Movements in the blood are detected by sensors in the cuff monitoring the movement through your brachial artery, then converting this into a digital reading.

No need for a stethoscope or manual inflation/deflation, which means it’s much easier to use.

In addition to your blood pressure, the 3 Series Upper Arm BPM also monitors your pulse rate. As with the wrist device, irregular heart beat detection is built-in, which is displayed as a warning signal on the screen.

The LCD display highlights all of the most important information, with large enough text to make each reading clearly visible. Unfortunately, there’s no backlight, but you can still view your systolic and diastolic blood pressure, pulse rate, and any irregular heartbeat warnings.

A ‘movement error’ symbol displays if your body moves too much during a reading, which is a feature all Omron blood pressure devices have.

As with the 3 Series wrist monitor, you don’t have a positioning sensor to help you find the best cuff height for an accurate reading. This is a feature that’s only available with the 7 Series.

In terms of the measurements, pulse is displayed from 40 to 180 beats/min, while pressure is displayed from 0 to 299 mmHg, with an accuracy of ±3mmHg.

Due to the additional power required, the 3 Series Upper Arm device requires 4 ‘AA’ alkaline batteries, compared to the 2 ‘AAA’ batteries needed by the wrist monitor. This powers an estimated 1000 measurements on one set of batteries, compared to just 300 with the wrist version.

What Do Other Reviews Say?

An important part of any BPM review is to consider the feedback from other people who have bought and used the device in their own home.

How easy was it to take a reading? Did they have a good experience with customer service? Was the reading accurate, and how comfortable was the cuff?

But reading through hundreds or even thousands of reviews can be time consuming.

That’s why we did the leg work for you.

Listed below you’ll find a summary of the pros and cons for the Omron 3 Series Upper Arm BPM, based on direct customer feedback.


  • Physician reported the device was more reliable than traditional methods, such as manometer and stethoscope
  • Easy to create a record of past blood pressure readings to discuss with doctors
  • Many users report results consistent with blood pressure readings taken at a doctor’s office
  • Very simple to use
  • Affordably priced
  • Easy-to-read display
  • Arm band is comfortable, and designed to suit a wide range of arm sizes
  • Portable and lightweight enough to bring to a doctor’s appointment if needed
  • Batteries last for a long time, and rechargeable batteries can be used
  • High level of trust in the Omron brand, in terms of product quality and blood pressure accuracy


  • Stores just 14 readings in memory, well below the 100-200 that are possible with Series 7 and Series 10 devices
  • No option to switch between different users
  • Some people with arms slightly smaller than the cuff found the systolic number to differ from their doctor’s machine. It’s important to check your arm size and use an appropriate cuff.
  • Isn’t supplied with an AC adapter for charging
  • Requires you to manually calculate an average. In contrast, the Omron 5 Series automatically displays the average of your last 3 readings taken within 10 minutes. CareTouch does something similar.

Omron 3 Series Review Summary

Overall Review Rating

4 / 5

So, is the Omron 3 Series Upper Arm BPM worth buying?

It's certainly cheaper than the wrist version, and fits a wider range of upper arm sizes than the Panasonic and Vive Health BPMs (7.75" to 15.75" and 8.75" to 16.5" respectively).

But with one user profile and the ability to store just 14 readings in memory, it's really only useful for day-to-day readings. If you want to measure your blood pressure for a month, then report the results back to your doctor, the 5 Series could be a better option (2 users, 100 total readings in memory).

The 5 Series usually costs just $15 more, but adds more memory, more users (2 total), advanced averaging, and a BP level bar to make readings easier to interpret. But perhaps most importantly, it also gives you the option to charge the device using an AC adapter, which is something the 3 Series fails to offer.

Looking ahead to the 7 Series, there isn't much of an upgrade over the 5 Series. Each user can store an additional 10 readings, there are lights to indicate your BP level, and the warranty increases from 2 to 5 years. All for around $12 more than the 5 Series.

That's why we recommend buying the 5 Series. It offers the best of both worlds, as a significant upgrade over the 3 Series, and better value for money than the 7 Series.
