How to choose a quality tonometer?

No wonder hypertension is called a dangerous enemy and a cruel killer. Increased pressure can lead to a stroke or a heart attack, so the level of pressure must be controlled. A special device, the tonometer, will help in this. How to choose it?

What to look for when choosing?

Useful thing

So, first you should pay attention to several important points:

  • How often are you going to measure? If only for prevention purposes once a week, then you can choose a simple and inexpensive model. If regular measurements are required, then give preference to proven instruments that provide high measurement accuracy.
  • Girth of the hand. If you have voluminous shoulders, then it is better to choose a carpal tonometer. Such models are worn on the wrist, which is quite convenient for many.
  • Price. Complex models, no doubt, will cost more, but such devices will enable to conduct accurate measurements without much effort. If you value accuracy, comfort and time, do not spare the money.If you do not plan to use the tonometer often, then it makes no sense to overpay.
  • Diseases. If you have any diseases of the cardiovascular system, then it certainly needs to be taken into account, since some models of tonometers have special functions that allow avoiding errors in certain ailments (for example, the result may be inaccurate in arrhythmia).

Types of tonometers

How to choose a blood pressure monitor? For a start, it is worthwhile to list the main types of such devices and their features.

Mechanical tonometers

At its core, a mechanical tonometer is the easiest option. The kit includes a phonendoscope, as well as a cuff with a rubber bulb and dial attached to it. The cuff is put on the shoulder or wrist, with the help of a pear a person pumps air into the cuff, which begins to squeeze the blood vessels, thereby catching the pulse with a stethoscope. The measurer should catch a knock and calculate the readings.


The mechanical tonometer is quite accurate, but only if the measurements are carried out correctly. And it is precisely the need to observe certain rules and create special conditions that explain the shortcomings of instruments of this type. We list them:

  • Full silence is required.Extraneous sounds and noises can interfere and distort the measurement results.
  • All the work should be done by the self measuring one, so if you need to measure the pressure yourself, the process can be complicated. Although over time, many manage to get used to and adapt.
  • In some models, the pear is so tight that a weakened or elderly person can force air into the air.
  • Air must be pumped in a special way. You can't do this too fast.
  • The air should also be gradually and slowly, some of it fails.
  • If the cuff is excessively squeezed, measurements will not be accurate.
  • It is necessary that the membrane of the phonendoscope is located exactly above the artery, otherwise the results will not be accurate.

The advantages of mechanical tonometers include low price and relative accuracy.

Automatic blood pressure monitors


Automatic blood pressure monitor - this is probably the most convenient option. Human participation is practically not required. You will only need to put a cuff on your shoulder or wrist, turn on the device and wait for the results. The device will independently force air into the cuff and remove it from there, as well as read the measurement results and display them on the display. We list the advantages of devices of this type:

  • No need for effort on the part of the measuring.
  • Ease of use. With the help of such a device it is easy and simple to make measurements yourself.
  • You can take measurements in almost any conditions, because noises and sounds will not interfere.
  • High measurement accuracy.

Now more about the disadvantages:

  • Electronic parts of the device can fail, especially if the quality of the device is low.
  • Automatic tonometers from batteries work, so they will need to be changed on a regular basis. But if you choose a model with the ability to connect to the network, then such a problem can be forgotten.
  • Pretty high cost.

Semi-automatic tonometers

Semi-automatic tonometer on the principle of measurement is similar to the automatic one, but the only difference is the need to force and deflate the air independently using a pear. The device will do the rest for you. Measurements are also carried out automatically using special devices, and the results are displayed. The cost of such a device will be lower than the price of an automatic blood pressure monitor. The disadvantages and advantages are the same as for automatic models.

Mercury Tonometers


Mercury tonometers appeared among the first and are still used in some medical institutions. They give accurate results, but are inconvenient to use and even dangerous as mercury can spill onto clothing. For home use, such devices are not exactly suitable, and it is almost impossible to find them on sale today.

Features of use

All the tonometers are used approximately equally, but in some the cuff is attached to the wrist, and in others - to the shoulder. Now for each option a little more.

  • Carpal tonometer is convenient to use and suitable for active people or owners of wide shoulders. But measurements may not be as accurate, especially in the presence of certain diseases.
  • The shoulder tonometer is less comfortable than the carpal. This option is not suitable for people with full or muscular arms. But this device is more accurate in measurements.


With pear

This seemingly non-essential element is very important. If you get a tonometer with a pear, then you will certainly appreciate it in use. If this detail is tight, then it will be quite difficult to inject air. So appreciate the pear in the work and only then make a choice.

Additional functions

Buying a tonometer, pay attention to additional features. Here are some of them:

  • Auto shut off. Many people forget to turn off the device after use, so this feature will be very convenient.
  • The ability to detect medium pressure. The device will make several measurements and calculate the average value. This feature will minimize the likelihood of errors and get an accurate result.
  • Memory. Some devices are equipped with a function of memorizing and systematizing the results, which will make it possible to keep a schedule and evaluate changes. Many devices allow you to record the date and even the measurement time. By the way, there are devices that can store data from two users, which is sometimes very convenient.
  • The arrhythmia indicator. A device with such a function will quickly detect heartbeat failures, display information about them on the display and re-measure for higher accuracy.
  • Some tonometers allow you to measure and pulse.
  • Voice playback of results. Such a function will be useful for people with poor eyesight.
  • The ability to transfer data to a computer or mobile device. If you need to keep a schedule, then this feature will come in handy.
  • If you need to monitor the pressure constantly, you should choose a tonometer with the possibility of regular periodic measurements without human intervention. The device will turn on and take measurements independently, as well as keep a schedule.

Let the high-quality and correctly selected tonometer help you monitor your health!
