A fluid filled bladder placed on the wrist was able to detect pulse; the pressure, which was necessary for the disappearance of the pulses, was measured with a mercury manometer.

The use of mercury manometers is often required in clinical trials and for the clinical measurement of hypertension in high risk patients, such as Pregnancy.

He also introduced the hydraulic testing of boilers, and the use of a mercury manometer to indicate the pressure.

This was useful as previous pressure gauges were unwieldy mercury manometers and the Bourdon gauge had yet to be invented.

A McLeod gauge isolates a sample of gas and compresses it in a modified mercury manometer until the pressure is a few mmHg.

The pressure transducer system was calibrated by mercury manometer at the beginning of each experiment, and was found to be linear and consistent throughout the range of pressures measured.

This eliminated the need for mercury manometers.

Aneroid sphygmomanometers (mechanical types with a dial) are in common use; they require calibration checks, unlike mercury manometers.

The pressure in this smaller volume is then measured by a mercury manometer, and, by knowing the compression ratio, the pressure of the original vacuum can be determined.

But now, he added, "for the first time in 100 years we are faced with some places' not having mercury manometers available for blood pressure measurements."
