Infrared thermography is a powerful tool, but its value lies in how effectively findings are communicated. A well-crafted, concise report transforms raw thermal data into actionable insights, enabling informed decision-making. Drawing from common issues observed in past reports, this guide provides practical tips to help you create clear and professional infrared thermal inspection reports that showcase your expertise while supporting maintenance and safety objectives.
While the included checklist covers the essentials, these tips are tailored for new thermographers who are just starting out and need a strong foundation for developing basic reports. As you gain experience, you can refine your reports by incorporating more comprehensive details and advanced analysis techniques.
DOs
FOCUS YOUR IMAGE
Focus your image, like the image on the right.
Keeping IR images focused is crucial for accurate temperature measurements, clear problem identification, and professional reporting. Focused images ensure precise data, make anomalies easier to spot, and improve client confidence in your findings. Consistently sharp thermograms enhance analysis and help you refine your skills as a thermographer.
Unfocused vs. Focused
HOW TO GET A SHARP IMAGE
For capturing finer details in your IR images, always move closer to your target when safe and practical. If the subject is too far, it would not be sharp enough.
Proximity improves image resolution, reduces the risk of missing critical anomalies, and enhances the accuracy of temperature readings. A closer view ensures your thermogram captures more precise details, making analysis and reporting more effective.
INCUDE RELEVANT INFO.
While infrared thermal cameras can capture extensive data, not all of it is relevant for every inspection. Focus on including only meaningful information, including labeling, that directly impacts your work. This approach minimizes distractions for clients and superiors, ensuring the report remains clear and actionable.
DO NOTS
DO NOT change your Emissivity Value
For most inspections, set your emissivity to 0.95, as this is a standard value suitable for many surfaces. However, be aware that some materials, such as reflective ones, will not display accurate temperatures due to their lower emissivity. This is where your training and understanding of material properties become crucial for accurate analysis. Always refer to your emissivity reference charts or adjust values when dealing with challenging materials.
As a thermographer, remember your role is akin to that of a “detective,” focusing on locating real potential issues rather than solely chasing precise temperature measurements. Prioritize identifying critical problems, such as electrical overheating, water leakages, or insulation failures, which are key indicators of underlying issues.
Keep in mind that using inconsistent emissivity values throughout your inspection can lead to discrepancies in your report, potentially misleading the reader. Consistent emissivity settings not only maintain the integrity of your thermal images but also enhance the clarity and reliability of your findings.
DO NOT use IR Fusion or MSX
Avoid using IR Fusion or MSX when starting out, as these features can make it difficult to determine if your thermogram is properly focused. Unfocused images can lead to inaccurate results.
To ensure clarity, keep IR Fusion or MSX turned off while learning, as it makes it easier to assess focus.
You can incorporate these features once you’ve gained more experience and are confident in capturing well-focused thermograms.
