Dual-Beam Ultraviolet PhotoMeter

The dual-beam UV spectrophotometer measures the sample beam and reference beam synchronously to offset the effects of light source fluctuations. It is used to detect the absorption characteristics of substances to ultraviolet and visible light, and to analyze solution concentration and composition in fields such as chemical engineering and environmental protection.
Selection
When selecting, focus on the wavelength range covering the detection needs and bandwidth matching the sample characteristics. Verify baseline stability and stray light indicators to ensure instrument sensitivity. Consider sample holder compatibility and the ease of use of the operating software to align with the laboratory's routine testing procedures.
