Double Beam Spectrophotometer ADDS-521 offers ± 656.1 nm wavelength accuracy for substance identification by absorbance peaks. It uses dual light paths to measure sample and reference simultaneously for high accuracy. This unit covers a broad wavelength range for UV and visible analysis. The double-beam design corrects light source fluctuations in real time for reliable measurements. Our Double Beam Spectrophotometer is used in pharmaceuticals, academic research, and chemical analysis for analysing the light absorption.
