This instrument is a laboratory analytical device designed for quantitative analysis of light absorption. It operates on the principle of **spectrophotometry** within the ultraviolet and visible spectrum ranges. The core construction typically utilizes high-grade optical glass or quartz cells to ensure precision measurements, adhering to international standards for spectral accuracy and wavelength stability.
Operators must ensure stable power supply and avoid direct sunlight exposure during operation. The light source requires periodic replacement based on usage hours to maintain calibration integrity. Regular cleaning of optical components with appropriate solvents is essential to prevent contamination and measurement drift.
