As we all know, the application principle of infrared thermal imager is to convert the invisible infrared energy emitted by the object into a visible thermal image, and measure the target temperature through the infrared transmitter and finally display it on the display screen. The birth of this simple, fast, accurate and safe high-end detection instrument is undoubtedly the gospel of many inspection and maintenance industries, but if the operation is not standard enough during the application process, it is easy to lead to inaccurate data, and even make the infrared thermal imager The service life of the application is shortened. So, in the application of infrared thermal imaging cameras, what needs to be paid attention to? Today, I will take you to learn.

First, adjust the focus. When using an infrared thermal imager, if the temperature of the background around the object to be measured is too cold or overheated, it will affect the accuracy of the temperature measurement of the object. Under normal circumstances, the infrared thermal imager application can adjust its curve after the thermal image is stored, but it cannot change the focal length after the image is stored, and naturally there is no way to eliminate other thermal reflections. Therefore, at this time, we need to adjust the focal length or measurement orientation to reduce or eliminate these effects. The Fluke thermal imaging camera application is equipped with a unique laser autofocus system, which can intuitively indicate the target position, suitable for repeated and multi-directional focusing operations.

Second, choose the correct temperature range. The temperature measurement range is one of the most important performance indicators for the application of infrared thermal imagers. Since the infrared thermal imager is used to detect and image the temperature of the purpose of measurement, the temperature measurement range can neither be too narrow nor too wide. For example, when the Fluke thermal imaging camera is used, the maximum temperature limit can reach 2000℃, and the minimum limit can reach -40℃. It should be noted that before the infrared thermal imager is used for temperature measurement, its temperature measurement range should be slightly adjusted to make it fit the temperature of the object to be measured as much as possible, so that the best image quality can be obtained.

Third, understand the maximum detection interval. In practice, the maximum detection interval is not a fixed data, and this interval is related to the size of the detected object and the performance of the infrared detector. If the same infrared thermal imager is used to measure an object with a relatively large area, the detectable distance is farther, and vice versa. Therefore, when we detect some smaller purposes, we must choose a suitable infrared thermal imager to ensure that the temperature detection is performed within a valid interval to prevent inaccurate data. Moreover, when detecting, the need and purpose of the infrared thermal imager should be kept at a moderate distance. No matter the distance is too large or too small, it will affect the use.

Fourth, keep the instrument stable. When we usually use mobile phones to take pictures, if we accidentally tremble, the pictures taken will be blurry. The same is true in the application of thermal imaging cameras. When pressing the storage button, you should be careful not to shake too much to ensure that the image is accurate and unambiguous. Or the instrument can be supported on a tripod, which is more stable.

Fifth, the detection environment should be single. Due to the distribution of the measured object, the working environment of the infrared thermal imaging camera application is often outdoors, so it is easily affected by weather elements. Of course, the atmospheric environment is immutable, so we can also make appropriate adjustments in advance according to the environmental characteristics to ensure the accuracy of the measurement data. In addition, you can also try to choose an environment without rain, fog, sunshine or at night, with no wind or low wind, so that there are no impurities or less impurities around, and unnecessary reflections can be avoided.

Sixth, operated by professionals. Professional equipment such as thermal imaging cameras is not easy to learn to operate, so in order to obtain the most accurate detection data, it is best to stop the operation by professionals. People can also discuss and learn from each other, and exchange experiences with each other.

Seventh, pay attention to regular maintenance and maintenance. After using any equipment for a period of time, there must be more or less problems, so regular maintenance and maintenance are necessary. Once a problem is found, it must be dealt with immediately to prevent a larger problem from appearing and bring more inconvenience to the later stage.
