1. Try to choose a video endoscope. Under normal circumstances, as long as the diameter of the probe is suitable, it is recommended to use a video endoscope, because the video endoscope has more advantages than the other two types of products in terms of image processing, storage management, and defect measurement, and is more convenient to use.
2. The cable should be as long as possible. The choice of wire length should not only consider the length of the pipe, but also consider that bends, silt, etc. will increase the length of the wire winding. The choice of length is to choose 5-10 meters as much as possible.
3. There should be room for diameter selection. According to the principle of industrial endoscopy inspection, the imaging device (such as a camera) needs to be sent to the area to be inspected, so the probe or insertion tube should be able to be inserted into the inspection channel relatively freely and can be withdrawn easily, so as to avoid scratching or scratching detection Channel, so the diameter selection must have a certain margin.
4. Portability considerations. To cope with the uncertainty of various testing environments, the integrated handheld portable endoscope has more advantages. Not only can one hand hold and control the buttons, but also it is convenient for the testing personnel to change positions freely at the testing site, just like using a portable computer in mobile office is a reason.
6. On the premise that the test can be carried out smoothly, you can choose a slightly larger diameter. On the basis of easy access to the detection channel, it is recommended to choose an endoscope with a slightly larger probe diameter, which is helpful to obtain better detection images. For example, a larger CCD array size can usually output more pixels.
The above lists the basic methods of selecting industrial endoscopes, and some details may not be covered. In general, to choose industrial videoscopes correctly, you need to understand the basic classification, application characteristics and core parameters of each product, and you also need to know the detection environment well. In more cases, it is often trustworthy to let professionals from well-known industrial videoscope manufacturers assist in the selection.
