The Omron BP742N 5 Series Blood Pressure Monitor is supplied with a cuff that fits upper arms from 9″ to 17″ in circumference.
Features include irregular heart beat detection, hypertension indicator bar, and clear systolic and diastolic readings via the large LCD screen. Up to 100 readings can be stored in memory for 2 users.
But how does it compare to some of the top rated Omron devices, such as the 7 Series and 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 decide whether the Omron 5 Series (BP742N) is the best home blood pressure monitor for you.
The Omron BP742N Blood Pressure Monitor uses the oscillometric method of blood pressure measurement. This means there are sensors that detect the movement of blood through your brachial artery and convert the result into a digital reading.
An alternative would be the auscultatory method. This is where you still wear a cuff, but a trained healthcare provider uses a sphygmomanometer and listens for the Korotkoff sounds using a stethoscope. The problem with this is that you’re relying on each doctor or nurse that you see applying the same technique, which isn’t always the case.
By using the Omron 5 Series at home yourself, you can guarantee that you’ve followed the same steps at the same time of day. This also allows you to minimize any external factors that could influence the reading.
The LCD screen displays your systolic and diastolic blood pressure, pulse rate, and blood pressure level (high, low, or normal).
There’s also a ‘movement error’ symbol, which activates if your body moves too much when measuring your blood pressure. Unfortunately, there’s no positioning indicator like you get with the Series 7 Wrist monitor, which prompts you to raise or lower the cuff position until it’s level with your heart.
Irregular heartbeat detection is another feature worth mentioning. If an irregular rhythm is detected more than twice when you’re taking a reading, the irregular heartbeat symbol is displayed on screen.
Battery Life and AC Adapters
Omron’s Upper Arm blood pressure monitors always have a longer battery life than their wrist monitors. That’s because they use 4 ‘AA’ batteries instead of 2 ‘AAA’, which means they have a battery life of 1000 measurements, compared to 300 with the wrist devices.
You’re also unable to charge using an AC adapter if you buy one of the wrist BPMs.
Fortunately, the Omron BP742N 5 Series has an AC adapter jack so you can plug the monitor directly into an electrical outlet for power.
Upgraded Features Compared to Omron 3 Series
The most obvious upgrade is the memory. You can now choose from two different user profiles, which isn’t a feature of the 3 Series.
Each user profile can store up to 50 readings, compared to just 14 readings for 1 user with the Omron 3 Series.
Another upgrade you can enjoy with the 5 Series is the averaging option. This is where you can take 3 readings within 10 minutes and display the average, which isn’t possible with the 3 Series.
One final upgrade is the blood pressure level indicator we mentioned earlier. Unless you’re already familiar with what your results mean, it can be difficult to know whether your blood pressure is high, low, or normal. This new indicator bar makes it easy.

Many of these devices already have thousands of highly rated reviews on Amazon, and they’re renowned for their excellent customer service.
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 5 Series Upper Arm BPM, based on direct customer feedback.
- Provides accurate, reproducible blood pressure readings
- D-ring cuff is suitable for a wide range or arm circumferences (smaller cuff available for arms that are 7″ to 9″)
- Cuff is easy to position, even if you’re taking your blood pressure on your own
- Large, easy to read results on the screen
- Stores many more readings in memory compared to the 3 Series wrist BPM (100 vs. 14)
- Allows you to store blood pressure readings for 2 users
- Easy to use – single button operation to start taking a reading
- Measures your heart rate at the same time as your BP, saving you time and money
- Excellent customer service from Omron
- Can be powered by an AC adapter or batteries
- High quality, lightweight construction
- Tube for the air pressure fits securely into the monitor
- AC adapter must be purchased separately
- Isn’t supplied with a carry case, but Caseling have a hard case you can buy
- Some customers with shorter arms had difficulty moving the cuff into position
- Display screen isn’t backlit, which makes it difficult to read blood pressure and pulse results in low light. If you need a backlight, we recommend the upper arm BPM from Vive Precision
- Bulk size makes it difficult to take with you while travelling. The Omron 5 Series is actually smaller than many upper arm BPMs, so if you need a device to take with you while travelling, we recommend the Omron 7 Series Wrist BPM (100 reading memory)
- Batteries supplied tend to run out of power after just a few readings, and aren’t rechargeable.
- Cuff isn’t as comfortable as the Omron 10 Series Upper Arm BPM (different material)
Omron BP742N Review Summary
Overall Review Rating
4.5 / 5
So, is the Omron 5 Series Upper Arm BPM worth buying?
The most important feature of any BPM is accuracy. If you don't get consistently reliable readings, it's useless.
Omron are the market leader in home blood pressure monitors, with tens of thousands of reviews on Amazon alone. They also continue to invest in this technology, introducing the Omron Blood Pressure Monitor + EKG™ at CES 2018 - the first blood pressure monitor for home use in the U.S. that can also measure EKG.
In our opinion, the 5 Series Upper Arm monitor provides the best balance of features and affordability, out of any home BPM currently on the market.
Although it has a slightly shorter warranty than the 7 Series and 10 Series devices (2 years vs. 5 years), the features are a significant upgrade over the 3 Series.
You get twice the user profiles, the ability to charge via an AC adapter, advanced averaging, and can store more than 7x as many readings in memory (100 vs. 14).
The 10 Series Wireless is the next significant upgrade, with memory that can store 200 readings, a 5 year warranty, TruRead automatic averaging, and Bluetooth data sync to selected iOS and Android devices.
But with a price that's usually $30 more than the 5 Series, it comes down to whether you find these extra features worth the money. If you don't need to store or refer back to data older than a few months, we would recommend the 5 Series.
