Which environmental conditions should be avoided when taking infrared readings?

Taking infrared readings requires specific environmental conditions for accuracy and reliability. Sunny, windy, and changing conditions can cause significant interference with the infrared measurements.

In sunny conditions, direct solar radiation can heat the surface being measured, leading to elevated temperature readings that do not accurately represent the object's normal operating temperature. Wind can introduce cooling effects, which also skew the data. Moreover, rapidly changing conditions can lead to inconsistent readings as the environment fluctuates. For example, if the temperature of the surroundings rises or falls during the measurement process, it can affect the thermal signatures detected by the infrared equipment.

In contrast, moist and humid conditions may not significantly distort the actual measurements but can affect the performance of the equipment itself. Cold and dry conditions, while they may present challenges, typically do not interfere with the infrared readings in the same way as sunny and variable weather. Nighttime readings can be perfectly valid if there is sufficient ambient light and proper setup, so they do not inherently pose a problem. Therefore, avoiding sunny, windy, and rapidly changing conditions ensures the integrity of infrared data collected for analysis.
