Moisture Mapping A Guide to Moisture Analysis and Measurement
Moisture Mapping
Moisture mapping is the process of creating a visual representation of the moisture content of a material or surface. This is typically done to identify areas of high or low moisture, which can be used to determine the cause of moisture problems or to monitor the drying process of a material.
Moisture Analysis and Measurement
Moisture analysis and measurement is the process of determining the moisture content of a material. This can be done using a variety of methods, including:
- Gravimetric method
- Electrical resistance method
- Capacitance method
- Neutron scattering method
What is the Best Measure of Moisture?
There is no single “best” measure of moisture, as the appropriate method will depend on the specific material being tested. However, some of the most common measures of moisture include:
- Moisture content (MC) is the ratio of the mass of water in a material to the mass of the dry material.
- Relative humidity (RH) is the ratio of the partial pressure of water vapor in the air to the saturation pressure of water vapor at the same temperature.
- Dew point is the temperature at which water vapor in the air begins to condense.
- Water activity (aw) is the ratio of the water vapor pressure of a material to the water vapor pressure of pure water.
