Benefits of Thermal Imaging for Water Leak Detection

Based upon the science of infrared energy, thermal imaging capture heat signature emitted from objects and formulate images based on the differences of temperature measurements.

The application of thermal imaging camera in facility maintenance, building diagnostic, house inspection and property pre-purchase check is fast gaining popularity over the years –

because this non-invasive technology can really help to ensure early detection of water leaks and moisture issues to prevent asset damage, while the avoidance of major repair cost can easily make the thermal camera pay by itself!
Additionally, thermal imaging camera is an excellent tool that offers many benefits on the job site, allowing home inspectors and plumbers to work more safely and efficiently.

Plumbers can do their jobs quickly and easier by utilizing thermal camera to uncover hidden leaks, survey water damage not easily visible, and pinpoint the exact location for repairs.

For instance, this video shows thermal imaging case studies that helped home inspector to identify hidden water and water damage issues that cannot be seen with naked eyes:


How to Choose Thermal Camera: Key Factors to Consider

When it comes to choosing an infrared thermal imaging camera for house inspection and home improvement activities (such as identifying area with moisture and water leakages), here are some key factors you should consider:

1. Thermal imaging sensor resolution determines the quality and clarity of the image. Higher sensor resolution will produce sharper image, as more pixels and data points are captured per unit of area.

2. Display: In addition to display resolution, some people prefer thermal cam with bigger screen size, whilst some would like to have touchscreen feature.

3. Frame rate, which refers to the rate at which the infrared detector creates images.
Most of the thermal cameras on the market today have 9 Hz refresh rate, means they create/refreshe image at a rate of 9 times per second.

4. Cost: Assess the price versus your actual needs and budget. For instance, a house owner who perform DIY home inspection once in a while may not want to spend over $1000 for a high resolution professional thermal imaging camera.

Depending on your intended application, other factors to consider include the thermal imaging camera’s measurement accuracy, temperature range, thermal sensitivity, battery life, and special features such as Wi-Fi connectivity.
