Ultraviolet-visible spectrophotometers have been widely used in scientific research, production, and teaching in various fields such as life science, materials science, environmental science, agricultural science, metrology, food science, geological science, petroleum science, medical and health care, iron and steel metallurgy, and chemical engineering.

Important aspects to consider when using a UV visible spectrophotometer:

1. Temperature and humidity are crucial factors affecting instrument performance. They can cause corrosion of mechanical parts, reduce the smoothness of metal mirrors, and lead to errors or performance degradation in the instrument's mechanical components. They can also cause corrosion of the aluminum coating on optical components such as gratings, mirrors, and focusing lenses, resulting in insufficient light output, stray light, noise, and even instrument malfunction, thus affecting the instrument's lifespan.

2. Dust and corrosive gases in the environment can also affect the flexibility of the mechanical system, reduce the reliability of various limit switches, buttons, and optocouplers, and are also a cause of aluminum coating corrosion on essential components. Therefore, regular cleaning is essential to ensure a clean and dust-free environment and instrument room.
