A moisture meter can come in which of the following models?

A moisture meter can indeed come in both invasive and non-invasive models. This versatility is crucial for different contexts in which moisture levels need to be measured, such as determining moisture in building materials or assessing dampness in a home.

Invasive moisture meters function by penetrating surfaces—typically with the use of probes—to provide a reading of moisture levels below the surface. This is particularly useful for assessing wood or drywall, where knowing the internal moisture content is important for detecting issues like rot or mold.

Non-invasive moisture meters, on the other hand, measure surface moisture without physically penetrating the material, often using electromagnetic waves or other technologies to determine moisture levels based on readings taken from the surface. This model is advantageous when there is a need to avoid damaging surfaces while still obtaining moisture information.

Having both types of meters available allows inspectors to select the most appropriate tool based on the situation, making this option the most comprehensive choice for assessing moisture in various materials effectively.
