🎁Automatic wrist tonometer LD-12S🎁
The electronic wrist tonometer with voice reproduction of LD12s results is designed to measure systolic and diastolic blood pressure and determine the pulse rate in people over the age of 15 years.
Due to the sound accompaniment, this model of tonometer is suitable for people with reduced eyesight.

The principle of operation:
🔹To measure blood pressure and pulse rate, the device uses an oscillometric method with Fuzzy Algorithm technology. A cuff with an electronic unit attached to it wraps around the wrist. 
🔹When the button (On/Off) is pressed, when the device is switched on, the cuff automatically inflates, then a measurement is performed during a slow discharge of air from the cuff. 
The sensor of the device detects slight fluctuations in pressure in the cuff produced by the expansion and contraction of the artery in response to each heartbeat.

🔹The amplitude of each pressure wave is measured, converted into millimeters of mercury and displayed on the LCD display as a digital value.

Features:
🔹Voice playback of results
voice playback volume control, voice playback language selection (Russian, English, French, Spanish, German)

🔹the Fuzzy algorithm takes into account the individual characteristics of the heartbeat
classification of measurement results in accordance with the recommendations of the World Health Organization (WHO)
large display with simultaneous indication of pressure, pulse, date and time of measurement
