The Omron tonometer is a common device for measuring pressure, which has proven itself to be quite reliable and does not give a strong error. The brand is Japanese, and the manufacturer guarantees the high quality of its equipment.
Modern materials used in the manufacture of these tonometers guarantee that the measurement error is completely absent or is no more than 2-3 units, which is insignificant.
Instructions are available for all models of tonometers included with them. It indicates what can provoke significant errors, and these factors must be excluded at the time of the procedure.
Semi-automatic tonometers
This budget option of equipment is most in demand. The price of such an Omron device can be from 1200 rubles. up to 2000 rub. depending on the specific brand and seller. In a semi-automatic tonometer, air is pumped into a cuff placed on the arm using a rubber bulb, which is pumped by the person measuring the pressure. Depending on the model, the device can be equipped with an arrhythmia indicator, a pulse counter and a memory that stores data up to the last 42 measurements. Instructions are included with all brands.
The advantages of semi-automatic machines are:
- measurement accuracy - there is practically no error,
- the ability to use it by persons with poor vision, since the display on which the indicators are displayed is large,
- the ability to do without a table - when taking measurements, it is not necessary to hold your hand with a cuff on it (the automatic device must also stand on the table itself),
- possibility of purchasing, if necessary, a cuff of an increased or decreased size - as standard it has an adjustable size from 22 to 32 cm.
A number of semi-automatic models are in particular demand.
Omron S1
The cheapest blood pressure monitor. Has memory for the last 14 indicators. Equipped with a case for storage and transportation. Reliability, durability and compact size make this semi-automatic an ideal travel option for people who need to constantly monitor blood pressure.
M1 Compact
The M1 Compact model, in addition to pressure, also determines arrhythmia if it occurs at the time of measurement. The device memory is enough for the latest 30 indicators. Its size is larger than the previous one, as is its weight. Storage case included.
M1 Eco
There is an indicator of arrhythmia. The pulse is recorded by an audio signal. The device memory is sufficient to save the last 42 indicators. The ability to determine average pressure based on these data is valued by hypertensive patients.
What types of Omron devices are better and more accurate?
Experts note the high accuracy, functionality, reliability, simplicity and ease of use of representatives of the entire Omron model range.
- To use tonometers at home, regardless of their type, you do not need to undergo special training.
- Large, clear information icons and numbers displayed on a multi-line display provide comfortable blood pressure measurement for users with low vision or hearing.
- The design features of Omron tonometers eliminate the need for repeated inflation and excessive injection of air into the cuff during the measurement process, which reduce its accuracy.
- Frequent calibration of devices is not required.
Therefore, the best Omron tonometer will be the one that meets the individual needs of the consumer, regarding, for example, the availability of additional options - motion indicators and cuff fixation, the ability to calculate average blood pressure.
According to an audit of medical devices, the M2 Basic model of the OMRON line of automatic tonometers took first place in Russia in 2020 in terms of sales volume among devices of its class, confirming such qualities as accuracy and reliability.
Automatic devices
Automatic devices do not have a bulb, and air is pumped into them without human action. In a similar way, air is deflated from the cuff after the measurement is completed. The person measuring blood pressure simply needs to put on the cuff and turn on the device. The devices operate from the network. An adapter for this is included in the package. The price of the device corresponds to the quality, and the more expensive Omron tonometer is better.
The M2 Basic assault rifle is the simplest budget model, costing about 2,000 rubles. This tonometer does not have memory for storing the results of several measurements, and the probability of error is about 5-7 units, which is considered quite significant.
M2 Classic
The M2 Classic device is functional and gives an error of no more than 3-5 units. Its cost is from 2000 to 2500 rubles. The model has a built-in memory for 30 measurements and shows the presence of arrhythmia if it is detected at the time of the procedure.
The M2 Plus model is almost the same, but its difference from the “classic” is the presence of an indicator that shows the correct fixation of the cuff.
M3 Expert
The cost of the device is around 3500 rubles. The cuff it comes with is universal. The device is equipped with sensors for recording arrhythmia and movement, as well as for correct fixation of the cuff. The device automatically determines the average pressure and stores up to 60 measurement results in memory.
M3 Family
A model that costs from 4,000 to 4,500 rubles, has a memory for 2 people and allows you to save results for each person for 60 measurements. The cuff is universal, which can be adjusted from 22 to 42 cm. There is a sensor for arrhythmia, movement and correct position of the cuff. Average pressure is calculated based on the results of the last 3 measurements.
Review of automatic tonometer models with reviews
When comparing different Omron blood pressure monitors and deciding which one is better, it is advisable to study not only the technical description, but also user reviews. This will help you get a more realistic idea of the devices and choose the best option.

Wrist devices
Compact electronic models of blood pressure meters that are easy and convenient to take with you. They are also great for people who have chubby hands in the elbow area, as well as increased fragility of blood vessels or diseases of the elbow joint. The cost of such devices is from 1500 to 3000 rubles. All wrist tonometers are characterized by:
- accelerated determination of pressure indicators,
- adjustable cuff from 13.5 cm to 21.5 cm,
- presence of a hand position sensor,
- the simplest possible use of the device.
The device always comes with a case for storage and transportation. Depending on the model, the memory is enough to save results from 60 to 90 measurements.
Such devices usually occupy leading positions in the ranking of the most convenient.
Important! Even very elderly people, for whom other equipment is difficult to operate, can master the control of them.
Which device should I buy for home use?
If there is no need to carry the device with you, but you need it for home use, then the best tonometer is a semi-automatic one with a cuff on the shoulder (on the arm above the elbow). The error in such models is minimal, and they record both low and high pressure equally well.
Attention! The service life of semi-automatic machines is much longer than that of automatic machines.
How to use the meter?
To ensure the accuracy of blood pressure measurements and the durability of the tonometer itself, it is recommended to strictly adhere to the requirements set out in the operating instructions supplied with the specific model of the device.
The general principles for using electronic pressure meters are the same:
- mobile phones should be turned off when measuring pressure, since electromagnetic fields can affect the accuracy of the device readings;
before the procedure, it is recommended to sit in a calm, relaxed position for at least five minutes;- During the measurement, the patient should not be in a state of tension or stress;
- the best position for self-monitoring of blood pressure is sitting, with back support;
- the cuff (with the exception of wrist tonometers) should be placed on the shoulder at the same level as the heart;
- to avoid isometric loading, it is necessary to have a support for the arm on which blood pressure is measured;
- there should be no fabric between the arm and the cuff;
- the measurement should be carried out in a room with comfortable environmental conditions for the patient;
- when using a semi-automatic tonometer, the rate of air inflation into the cuff should be moderate;
- blood pressure indicators, if it was measured directly after physical activity, eating and drinking alcohol, smoking, or water procedures, may be inaccurate.
Features of choice
When choosing a device for measuring blood pressure, even from the most reliable options, you need to take into account some individual characteristics so as not to encounter the fact that in the future the procedure will be uncomfortable, which will increase the error.
- Cuff size. In all tonometers, this part is adjustable, but if a device is needed to determine pressure for a very obese person or child, then the average size will be unsuitable. You will need to purchase an additional cuff, or you need to choose a model that comes with several replacement cuffs of different sizes. Before purchasing, you should measure your arm circumference in the right place in advance.
- The size of the display should be comfortable for the user of the device. For older people, the larger the numbers, the better. In most cases, they need the device for home use and, therefore, there is no need to choose the smallest one.
- Memory size. If pressure monitoring is needed periodically - only when you feel unsatisfactory, then there is no point in overpaying for the device’s memory, which allows you to save the readings.
Before purchasing the device, you must carefully inspect it. There should be no defects or damage on it. If there are doubts about the proper quality of the device, it should be abandoned.
Conclusion
First of all, the Omron HeartGuide tonometer wristwatch is designed for people who need to constantly measure blood pressure and pulse, but do not have a professional medical device with them.
Secondly, a wearable gadget can always be on your hand, so you can monitor your health at any time and anywhere. The device also has full fitness tracker functionality and a smartwatch-style design, so calling the Omron HeartGuide a watch is quite correct. Especially considering the cost – $499 (for the US market).

- No
What causes errors in indicators?
Inaccurate data may be noted when measuring blood pressure in the following cases:
- violation of the rules of conduct during measurement - activity, conversation, watching TV,
- low level of battery charge in the device - when they run out, there may be malfunctions,
- poor quality cuffs - old, they may not create the required level of compression and begin to leak air,
- device problems.
During the day, slight fluctuations in blood pressure are normal. This is not a disease or evidence that the device is faulty.
