An air pressure measuring device is called a Barometer.
The higher the elevation the lower the air pressure. Sea level is considered the standard for air pressure measurement.

Millibars (mb.) you can use that measurement to measure Air Pressure. The NWS uses mbs to measure the air pressure inside a hurricane.
Mercury Barometer
Atmospheric pressure is caused by the weight of air above the measurement point. At 30,000 feet in the sky, the air pressure on the outside of the airplane will be much lower than it was nearer the ground.

A sphygmomanometer is a device used to measure blood pressure. A more common name for this device is a blood pressure meter.
Sea level pressure.
The higher the elevation the lower the air pressure. Sea level is considered the standard for air pressure measurement.
Yes. The fluid may be flowing backwards or there may be obstructions or distortions in the pressure-sensing lines between the primary measurement device and the secondary measurement device.

There are any measuring devices available, your question should be little specific. Measuring device is for electricity or water or earth quake or data traffic or air pressure.
the common measurement of air pressure used by meteorologists is the isobar
The humidity is measured by a device called a hygrometer.

No, the Fujita scale rates tornadoes from F0 to F5 based on the severity of their damage. It is a system, of assessing tornadoes, not an actual measurement device. A barometer is an instrument that measures air pressure.
