You can take a look at Olympus handheld industrial endoscopes. Our company is an aero-engine supporting manufacturer and has extremely strict quality requirements. We have used many brands, large and small, and really feel that Olympus's handheld industrial endoscopes are of better quality and the products are more durable. Like the IPLEX NX, which has an 8.?4-inch touch screen display, it can deliver clear and bright images in any light, and it has an image 1.7 times larger than a traditional 6.5-inch display. Even in dark places, or places with strong reflections, subtle defects can be detected over large areas with bright and clear images. Regardless of the quality or the clarity of the inspection images, they are among the best in the industry.
