### Moisture Monitoring Equipment Moisture mapping is a crucial technique to uncover hidden moisture and detect potential water damage before it becomes a costly problem. This practice involves using specialized equipment to accurately measure moisture levels in various materials, including wood, drywall, and concrete. ### What is a Moisture Tester Called? Moisture testers, also known as hygrometers or moisture meters, are the key tools in moisture mapping. These devices are designed to provide real-time readings of moisture content. They are typically equipped with sensors that respond to changes in electrical resistance, capacitance, or microwave absorption, which are indicators of moisture presence. **Types of Moisture Testers:** - **Pin-type meters:** Insert pins into the material to measure moisture below the surface. - **Non-invasive meters:** Use sensors to measure moisture without damaging the material. - **Infrared cameras:** Detect temperature differences that can indicate moisture accumulation.
