2. Moisture meter - Wikipedia

   en.wikipedia.org/wiki/Moisture_meter

   Measuring water leakage in exterior wall with Trotec T660 Moisture Measuring Device, using dielectric measurement method (indicative). Moisture meters are measuring instruments used to measure the percentage of water in a given substance, as physical properties are strongly affected by moisture content and high moisture content for a period of time may progressively degrade a material.

3. Moisture vapor transmission rate - Wikipedia

   en.wikipedia.org/wiki/Moisture_vapor...

   Moisture vapor transmission rate (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers .

4. Hygrometer - Wikipedia

   en.wikipedia.org/wiki/Hygrometer

   A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.

5. Soil moisture sensor - Wikipedia

   en.wikipedia.org/wiki/Soil_moisture_sensor

   A simple soil moisture sensor for gardeners. Soil moisture sensors measure the volumetric water content in soil. [1] Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighing of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant ...

6. Moisture analysis - Wikipedia

   en.wikipedia.org/wiki/Moisture_analysis

   Moisture dew point is the temperature at which moisture condenses out of a gas. This parameter is inherently related to the moisture content, which defines the amount of water molecules as a fraction of the total. Both can be used as a measure of the amount of moisture in a gas and one can be calculated from the other fairly accurately.

7. Water activity - Wikipedia

   en.wikipedia.org/wiki/Water_activity

   The water in food has a tendency to evaporate, but the water vapor in the surrounding air has a tendency to condense into the food. When the two tendencies are in balance— and the air and food are stable—the air's relative humidity (expressed as a fraction instead of as a percentage) is taken to be the water activity, a w .
