To make the measuring apparatus a managable size i.e approx 10 inches high for Mercury tube. If water was used the tube would need to be much larger and the apparatus would be unmanageable when being carried around.

A sphygmomanometer is also known as a mercury pressure device. It works by a mechanical manometer made of mercury that measures the pressure.
Sphygmomanometer (the correct spelling).A Sphygmomanometer is an instrument used to measure an individuals indirect blood pressure. They generally consist of an inflatable cuff that fits around a limb (normally the arm, just above the elbow), a bulb for controlling air pressure within the cuff, and a mercury or aneroid manometer (a dial stating the pressure in millimeters of mercury, mmHg).
It is used to measure blood pressure - it's the inflatable blood pressure cuff you see at the doctors.
A sphygmomanometer or blood pressure meter (also referred to as a sphygmometer) is a device used to measure blood pressure, composed of an inflatable cuff to restrict blood flow, and a mercury or mechanical manometer to measure the pressure. It is always used in conjunction with a means to determine at what pressure blood flow is just starting, and at what pressure it is unimpeded. Manual sphygmomanometers are used in conjunction with a stethoscope. The device was invented by Samuel Siegfried Karl Ritter von Basch in 1881. Scipione Riva-Rocci introduced a more easily used version in 1896. In 1901, Harvey Cushing modernized the device and popularized it within the medical community.

A sphygmomanometer is also known as a mercury pressure device. It works by a mechanical manometer made of mercury that measures the pressure.
Mercury is a heavy, silvery-white metal.Due to the high density of mercury a rise in small column of mercury can exert much pressure. so it is used to measure pressure as a small tube is sufficient to measure a considerable pressure.More over Mercury does not stick to the glass surface inside

The correct spelling is "sphygmomanometer."
The 3 types are: Manual, Digital and Aneroid.
Sphygmomanometer.
Mercury's density is around 13.54 x that of water, so the pressures (in mm of water) would be 13.54 x what they are for mercury - 100 mm Hg would be around 1354 mm H2O
A sphygmomanometer is typically used along with a stethoscope to measure blood pressure. Therefore, it is an extension of the ear.
