The image shows a close-up of a pressure gauge on display in a glass case. The gauge is made of metal and has a round face with a white background and black numbers and markings. The dial is mounted on a metal base with a threaded nipple at the bottom. On the right side of the gauge, there is a small metal tool with a black handle and a silver body. The tool appears to be a wrench or a screwdriver. There is also a small plaque with Chinese characters on it next to the gauge.
