This blood instrument instrument looks classic but is modern in function. It is known as a mercury instrument, but it does not have mercury at all. The instrument marks both systolic and diastolic pressure when measuring the person's blood pressure, providing a more precise result. The instrument also gives the individual's pulse rate automatically after taking the blood pressure. It has a functional housing, making it easy to carry around. Furthermore, it has a standard cuff that is appropriate for arms with 22 to 32 cm circumference. The instrument comes with batteries. Our two-tube cuffs that come in different sizes can also be connected.
