Water Damage Restoration
Non-penetrating Meter
In the water damage restoration industry, the non-penetrating meter is primarily used for measuring moisture content (MC) in sheetrock walls or ceilings and hardwood flooring. It can also be used to measure MC in concrete, plaster and laminate flooring. This meter can either use a radio frequency to measure MC or the more common type uses conductive pads. When excessive moisture is present this completes the circuit across the insulated pads and the meter will register the item as having excessive MC. This meter is also commonly referred to as a pin- less or non-destructive type moisture meter.
The Pin-type Meter
The pin-type meter is the most accurate way to measure the moisture content (MC) of a material.
This type of meter, also known as a penetrating meter, measures moisture by the electrical
resistance measured between the two pins (or electrodes) inserted into the material in question.
