The tonometer market is literally packed with low-grade products. The ubiquitous Chinese manufacturers are striving to create as many blood pressure devices as possible at a very low price tag. Most often, such devices produce results that are far from the truth. If you want to get the most accurate blood pressure monitor, then buy one of the models that are discussed in our selection. We tried to talk about both mechanical and electronic blood pressure monitors, so it will be quite easy to make a choice.

Rudolf Riester Precisia N

Rating: 4.9


Our review consists exclusively of those blood pressure monitors that you can easily buy in Russian retail. This allows you not to wait for delivery from abroad for one to two months. But with Rudolf Riester Precisia N, there may be some problems. This is the best mechanical tonometer, the accuracy of which is extremely high. Because of this, the device is in great demand, which has led to a certain shortage. Now it is quite difficult to find this model in stores. But if you do find it on the shelves, take it without hesitation!

Outwardly, the tonometer is nothing unusual. You understand the main advantage of the device after you begin to feel it. Only high quality materials are used here! There are no complaints about the scale showing the current pressure. The air is shut off by rotating a fairly massive metal wheel. Even the rubber bulb does not raise any questions – it fits comfortably in the hand, and the required air pressure can be achieved after a few clenches of the fist. As for the stethoscope, polished metal was used in its production, giving out a pleasant shine to the eye.

If you read the operating instructions, it becomes clear that the device still has some measurement error. However, it does not exceed 2 mm Hg. Art. This can be considered a very meager number.

It may seem that this tonometer has no flaws at all, but it is not. This model is not universal. Its cuff, which has a velcro strap around the shoulder, is quite large. This means that this tonometer is unlikely to be used to measure blood pressure in a child. More precisely, the size of the cuff is adjustable from 32 to 48 cm.


  • Minimum measurement error;
  • The best materials were used;
  • Rapid pressure build-up;
  • High-quality dial gauge;
  • A built-in stethoscope is used.


  • The size of the cuff will seem too large to some;
  • High price.

Omron M3 Expert

Rating: 4.8


Some people are familiar with the Omron brand. A variety of medical equipment is produced under it – for example, nebulizers. Therefore, it is easy to guess that the Omron M3 Expert is an automatic tonometer. It works from the mains or batteries, independently pumping air and assessing the human pulse. You just have to put on the cuff on your arm. Its size, by the way, varies from 22 to 42 cm. This means that the device can measure pressure even in a child. Only all sorts of bodybuilders, whose arms are swollen to incredible sizes, are left behind.

This tonometer has a very large display. Basically, only all kinds of numbers are displayed on it. Their font is such that even a person with poor eyesight, who has lost his glasses somewhere, can see the result. There are also a number of buttons on the body. This makes it clear that the device is equipped with additional modes. Indeed, the Omron M3 Expert provides a multi-measurement mode, and it also knows how to remember the previous result. And not one, but as many as 60! This is how many memory cells are built into this device.

Unlike cheaper counterparts, this tonometer takes into account the state of the patient's vessels. It calculates the pressure based on different indicators, providing the most accurate value. This is why the Omron M3 Expert is used even in huge medical facilities where false readings are unacceptable.

As mentioned above, the device can operate both from the mains and from batteries. In the second case, you will need four AA batteries, which, by the way, can be found in the box with the product. As for the mains adapter, it is also supplied with the device. The instructions say that this model still has some measurement error. However, it does not exceed 3 mm Hg. Art. It is unlikely that you can find an even more accurate tonometer in stores.

Above, we have already said a few words about the configuration. But it should be noted that it is supplemented by some other things. For example, a customer will receive a blood pressure log. It will allow you to analyze your health and understand what factors affect his condition. And in the box with the device there will be a cover that allows you to protect the Omron M3 Expert from dust.


  • The warranty period has been extended to five years;
  • Rich equipment;
  • The display shows numbers in large print;
  • The cuff is suitable for children and adults;
  • Battery powered possible;
  • Very high measurement accuracy;
  • The device is capable of storing measurement results;
  • The state of the vessels is taken into account.


  • Very high cost.

B.Well PRO-35 (M-L)

Rating: 4.7

B.WELL PRO-35 (M-L) .jpg

Another tonometer, often found in large medical institutions. It also works in automatic mode. The results are displayed here on a fairly large digital display. It's nice that he is enlightened, thanks to which the numbers are clearly visible in any conditions.

To the left of the screen, you can see a color scale. With its help, you can understand whether your pressure is in order – after the measurement, the device puts a mark near the corresponding color segment. If the mark is opposite the red area of ​​the scale, then call your doctor immediately!

As expected, the device received several buttons. One of them allows you to measure your heart rate, which is sometimes useful. Also you can compare the measurement result with the previous indicator. At the same time, the device does not even force you to specially store the numbers in memory – this is done automatically. There are 30 memory locations in total, which is enough to store a whole month of measurements, even if they are carried out every day.

The tonometer uses a universal cuff adapted to the shape of the arm. Its size varies from 22 to 42 cm. It can be safely said that the device is capable of measuring pressure even in a child! The device uses an electric motor to pump air. This means that B.Well PRO-35 (M-L) needs to be supplied with electricity. This is done by connecting it to the mains, or by installing four AAA batteries.

Otherwise, this is a typical blood pressure monitor sold for little money. I am glad that its measurement error does not exceed 3 mm Hg. Art., which corresponds to approximately 5% of human blood pressure. Well, the only upsetting is the warranty period, which here is equal to the usual year. However, the reviews indicate that the device almost never fails. Well, the marriage can be detected at the first use. For example, one of the buyers came across a copy that works only from the network – it discharges the batteries in literally one day. But this, of course, is an isolated case.


  • Suitable for both adults and children;
  • Battery powered possible;
  • Very low measurement error;
  • There is an arrhythmia indicator;
  • Small size and weight;
  • The price tag is not particularly high;
  • Remembers previous values.


  • Backlighting would be nice.

AND UA-911

Rating: 4.6

AND UA-911.png

Modern technologies are entering the world of medical devices. This is the description that can be given to the tonometer called AND UA-911. The fact is that this model is one of the few equipped with Bluetooth – a module. It allows the device to transfer data to a smartphone, then viewing it in a special application. It is thanks to this innovation that you can refuse to independently maintain a journal in any notebook.

Unfortunately, due to the Bluetooth – module, the device turned out to be very expensive. In pharmacies and shops, they ask for more than three thousand rubles! However, the device does not look elite. It received a display, but it is rather small. However, it cannot be called absolutely miniature – even a person with poor eyesight should consider the numbers on it.

Pressure measurement is carried out using a universal cuff. Its sizes vary from 23 to 37 cm, which allows us to hope for a successful blood pressure measurement even in a child. The device also allows you to find out the current heart rate, for which you need to press the appropriate button.

Like the specimens considered above, AND UA-911 has a measurement error of 3 mm Hg. Art. This makes the device as accurate as possible. The numbers shown by the device are immediately stored in the memory. Pressing the corresponding button allows you to view the previous results, comparing them with those shown right now. In total, the tonometer received 30 memory cells.

It's nice that the device is capable of boasting an arrhythmia indicator. The operation of the device is provided by the power supply, the power adapter is supplied in the kit. But if this option does not suit you, you can insert four 'finger' batteries into a special compartment. It is in the autonomous mode that the tonometer is used by many doctors working in hospitals and clinics.


  • It is possible to transfer readings to a smartphone or tablet;
  • Works not only from the mains, but also from batteries;
  • Very low measurement error;
  • There is an arrhythmia indicator;
  • A universal cuff is used;
  • The device stores the results of the last measurements.


  • The display could be larger;
  • High price;
  • There is no power supply included.

Omron M6 Comfort

Rating: 4.5


One of the thinnest and smallest blood pressure monitors among those working in automatic mode. At the same time, there was still room inside it for four AA-batteries. The device can also be operated from the mains, the power adapter is supplied in the kit

The device has a familiar digital display. There was a place on it not only for the measurement result in numerical terms, but also for the arrhythmia indicator. The device also offers information on the current heart rate; to measure it, you just need to press one button. However, pressing one button is enough to measure blood pressure.

As befits all blood pressure monitors included in our rating, Omron M6 Comfort has a low measurement error. Also, the device can memorize up to one hundred of the last measurement results. Moreover, there is a pressure measurement mode for two people! This means that the device will store the results of both the husband and the wife and mark them accordingly. It should be noted also the support of the patented technology, thanks to which the system makes an adjustment for the state of the patient's vessels.

The device works with the usual universal cuff, the sizes of which vary from 22 to 42 cm. The system is equipped with an indicator of the correct cuff fixation, which many other devices of this type cannot boast of.

Above we have already talked about the automatic tonometer, which has a five-year warranty period. Well, the creators of the Omron M6 Comfort went even further. They provide the buyer with a 10-year warranty! The device is also capable of boasting a rich package bundle. It includes a diary for recording blood pressure, a case for storing the device, an instruction manual and a set of batteries.

Unfortunately, there are defective copies of this device on sale. They give the wrong result, being 15-20% wrong. Therefore, after the purchase, it will not be superfluous to compare the device with what a traditional mechanical tonometer, borrowed for this from one of friends or relatives, will give out.


  • Battery powered;
  • A universal cuff is used;
  • Very high measurement accuracy;
  • Can store measurement results of two people;
  • There is an arrhythmia indicator;
  • Rich equipment;
  • Very long warranty period.


  • There are defective copies;
  • Difficult to find on sale.

B.Well PRO-39

Rating: 4.4

B.WELL PRO-39.jpg

Another automatic tonometer ends our selection. It has the same principle of use: you only need to put the cuff on your arm (this time on the wrist), and then you have to press a very large button. All that remains is to wait for the result, which will be displayed on the digital display. Alas, there is no auxiliary data on the screen, in this regard the device is noticeably simplified. But on the other hand, the tonometer is sold for only 1,500 rubles, and it is powered by only two 'little finger' batteries.

It should be noted that this copy is definitely not suitable for bodybuilders and athletes. The fact is that the size of the cuff here varies from 14 to 19.5 cm. However, this model is, after all, designed to be placed on the wrist, so the above statement is controversial.

B.Well PRO-39 shows the current heart rate as usual. Also this model is very accurate. There is a pressure measurement error, but it does not exceed 3 mm Hg. Art. And this tonometer also remembers the result of the last measurement, which allows you to understand if your condition has improved.

It remains to add that the tonometer turned out to be compact from light. This is by far the smallest representative of our collection. The only sad thing is that the manufacturer provided his creation with the usual warranty period, which is exactly one year. However, it is difficult to imagine that this device will suddenly fail for some reason.


  • Minimum dimensions;
  • Requires very few batteries;
  • There is an arrhythmia indicator;
  • The result of the last measurement remains in memory;
  • Very low measurement error.


  • Minimal functionality;
  • Cannot work from the mains;
  • Not all hand positions are measured correctly;
  • Not suitable for people with atherosclerosis;
  • There are defective copies.


Now you know which blood pressure monitors are worth paying attention to. All models reviewed here are the best of the best. Their result is as accurate as possible. At the same time, they have a different price tag, so you just have to understand how much you are willing to spend.
