In addition to integrated sensors, A9 is also equipped with FLIR's unique MSX technology, and is equipped with a 5-megapixel camera to generate thermal images. Based on the difference in object temperature, A9 can create clear thermal images and visualize temperature and heat. A9 can not only detect the temperature of the object, but also set up to 5 temperature measurement points, which is convenient for users to record the temperature data on the screen.
