Double Beam Spectrophotometer ADDS-515 analyses samples in the visible to near-infrared range from 190 to 1100 nm. It supports multiple cell holders for a variety of sample types and testing conditions. The sample and reference beams are measured simultaneously to minimize lamp fluctuation errors. This unit comes with built-in self-diagnostic functions for system monitoring. Our Double Beam Spectrophotometer is used in clinical diagnostics, research labs, and educational institutions for accurate absorbance-based analysis.
