Introduction

Moisture Mapping, also known as Moisture Investigation or Moisture Assessment, is a process by which professionals identify and locate sources of moisture and water intrusion in buildings and structures. It involves utilizing specialized equipment and techniques to detect, measure, and analyze moisture levels within different building components and materials. Moisture Mapping plays a crucial role in preventing and mitigating moisture-related issues, such as mold growth, structural damage, and indoor air quality problems.

Moisture Monitoring Equipment: A Comprehensive Guide

Numerous types of equipment are employed in Moisture Mapping to accurately measure and assess moisture levels. Each instrument serves a specific purpose and is designed to detect moisture in various forms and locations. Here is a brief overview of commonly used Moisture Mapping equipment:

1. Moisture Meters

Moisture meters are handheld devices that provide instant readings of moisture content in building materials. They utilize different technologies, such as electrical resistance, capacitance, or thermal conductivity, to measure moisture levels and display readings on a digital or analog scale.

• Pinholes: Used to measure moisture levels in wood and other porous materials by inserting two pins into the surface.
• Non-invasive moisture meters: Utilize electromagnetic waves to measure moisture without damaging the surface of the material.

2. Hygro-Thermometers

Hygro-thermometers simultaneously measure temperature and relative humidity levels in the air. This information is crucial for identifying areas with excessive moisture and potential condensation problems.

• Dry bulb temperature: Measures the actual temperature of the air.
• Wet bulb temperature: Measures the temperature of the air when it is cooled by evaporation.
• Relative humidity: Calculated from the dry and wet bulb temperatures.

3. Thermal Imaging Cameras

Thermal imaging cameras detect and visualize temperature differences on surfaces. This enables professionals to identify areas with moisture problems, as wet areas tend to have lower surface temperatures than dry areas.

• Infrared radiation: Thermal imaging cameras capture infrared radiation emitted by objects.
• Thermal images: Displayed on a screen, they show temperature variations as different colors.

4. Leak Detectors

Leak detectors are used to locate the source of water leaks in pipes, plumbing systems, and building envelopes. They employ various technologies, such as acoustic, ultrasonic, or tracer gas detection, to pinpoint the exact location of the leak.

• Acoustic leak detectors: Identify leaks by listening for water flowing through pipes.
• Ultrasonic leak detectors: Detect high-frequency sounds produced by water leaks.
• Tracer gas leak detectors: Utilize a tracer gas to locate leaks in sealed systems.

What is a Device that Measures the Moisture Content in the Air Called?

A device that measures the moisture content in the air is called a hygrometer. Hygrometers are commonly used in Moisture Mapping to assess relative humidity levels and identify areas with excessive moisture. They come in various types, including:

• Mechanical hygrometers: Utilize a mechanical sensor that expands or contracts with changes in humidity.
• Electronic hygrometers: Measure humidity using electronic sensors, providing accurate and real-time readings.
