The most usual devices are barographs and barometers. A barometer can work off an aneroid cell (eg digital aneroid barometer) or a column of Mercury (eg Kew Pattern barometer). Barographs usually work off aneroid cells and through a linkage system print the pressure onto a chart (usually changed weekly although there are daily barometers as well). So the main difference is that a barometer gives a spot reading while the barograph is continuous, although it's possible for the readings from a digital barometer like one connected to an Automatic Weather Station to be saved and called up later, or even printed out in graph form.
The usual unit for air pressure in meteorological circles is the hectoPascal (hPa) which replaced the millibar some years ago (the units have the same numerical value, though) except for the US which sticks with the old inches of mercury (InHg).

Collect the Differences between a barometer and manometer?
barometer is used to measuring atmospheric pressure. manometer is used to measuring the pressure of gases.
What is graduated measuring device?
Graduated measuring devices have a set of marking on them on the linear or angular scale to which an object feature can be compared to for measurement.
Is 1 milliliter same as 1.0 milliliter?
Pretty close, but 1.0 ml is more accurate. The way measuring works, if your measuring device only reads in whole numbers, you can have a fair bit more than 1 ml before your measuring device ticks over into 2 ml. But if your measuring device reads tenths, then it'll tick over from 1.0 into 1.1 pretty fast, and you'll get closer to your target volume.
What are verners?
Verners are a measuring device used to measure size that is based on the log scale.
What does a compound pressure gauge measure?
A compound pressure gauge measures both positive and negative pressures relative to atmospheric pressure. It typically consists of two pressure sensors, one for measuring positive pressure (above atmospheric pressure) and one for measuring negative pressure (below atmospheric pressure). This type of gauge is commonly used in applications where both types of pressure need to be monitored, such as in HVAC systems or industrial processes.
What happens when intraalveolar pressure exceeds atmostpheric pressure?
lung at rest
What is a osmometer?
A device for measuring osmotic pressure
What is the definition of barometer?
An instrument for measuring atmospheric pressure, used especially in weather forecasting.
What is a blood pressure dinamap?
a blood pressure measuring device that largely replaced sphygmomanometers
Which is the air pressure measurement device?
A barometer is the device used to measure air pressure. It works by measuring the weight of the air pressing on a surface. High air pressure typically indicates fair weather, while low pressure often signals stormy conditions.
What sphygmomanoneter use for?
it is the device used for measuring the blood pressure in human body.
What was the device that Torricelli invented for measuring air pressure called?
The device that Torricelli invented for measuring air pressure is called a barometer. It works by balancing the weight of the atmosphere with the weight of a column of mercury in a glass tube.
What is an applanation?
An applanation is a flattening of the cornea, especially by the application of pressure.

How many meters deep is 10 barometers?
A barometer is a device for measuring atmospheric pressure - NOT distance or depth !
What is the pressure measuring device invented by a frenchman in the 18th century?
In 1849, the Bourdon tube pressure gauge was patented in France by Eugene Bourdon.
