what instrument is used to measure moisture in the air?

A hygrometer is an instrument used to measure relative humidity. Humidity is the measure of the amount of moisture in the air. A psychrometer is an example of a hygrometer.

A snow gauge is an instrument used by meteorologists and hydrologists to measure the amount of snow precipitation over a set period of time. Snow stakes and simple rulers can be used to determine the depth of the snowpack, though they will not evaluate either its density or liquid equivalent.

A barometer is an instrument for measuring the pressure of the air, due to the weight of the column of air above it.

Water activity is equal to equilibrium relative humidity divided by 100: (a w = ERH/100) where ERH is the equilibrium relative humidity (%). Relative humidity sensors of great variety are available for this purpose, including electric hygrometers, dewpoint cells, psychrometers, and others.

A variety of instruments can be used to measure wind direction, such as the windsock and wind vane. Both of these instruments work by moving to minimize air resistance. The way a weather vane is pointed by prevailing winds indicates the direction from which the wind is blowing.

A rain gauge (also known as an udometer, pluviometer, or an ombrometer, or a cup) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over an area in a predefined period of time.

Absolute humidity is the measure of water vapor (moisture) in the air, regardless of temperature. ... Relative humidity also measures water vapor but RELATIVE to the temperature of the air.

An aneroid barometer measures air pressure without using liquid. A mercury barometer measures air pressure using liquid mercury.

You can easily measure the salinity of sea/ocean water using an instrument called a refractometer, which measures the index of refraction of a particular substance. It is a device used in geology, medicine and agriculture. Set up your refractometer device by dropping three drops of distilled water on its meter.

Absolute humidity is the measure of water vapor (moisture) in the air, regardless of temperature. It is expressed as grams of moisture per cubic meter of air (g/m3). ... It is expressed as the amount of water vapor in the air as a percentage of the total amount that could be held at its current temperature.

An anemometer is a type of weather instrument that measures wind speed. Some of these instruments measure both wind speed and wind direction. Anemometers are common at weather stations. A cup anemometer is a type of instrument that uses three or four hemispherical cups mounted on horizontal arms on a vertical rod.

An anemometer is an instrument that measures wind speed and wind pressure. Anemometers are important tools for meteorologists, who study weather patterns. They are also important to the work of physicists, who study the way air moves.

A RAIN GAUGE measures the amount of rain that has fallen over a specific time period. A WIND VANE is an instrument that determines the direction from which the wind is blowing. An ANEMOMETER measures wind speed. The cups catch the wind, turning a dial attached to the instrument.

The speed of that wind can be measured using a tool called an anemometer. An anemometer looks like a weather vane, but instead of measuring which direction the wind is blowing with pointers, it has four cups so that it can more accurately measure wind speed.

Moisture also refers to the amount of water vapor present in the air”. And as you can see, when we talk about the amount of moisture in the air, then this is called humidity. Basically, when we talk about the presence of water vapor in the air, there is really nothing different between moisture and humidity.
