721S Visible Spectrophotometer
Visible spectrophotometer is a scientific instrument that measures the intensity of light as a beam of light passes through a sample solution. It is used to measure how much a chemical substance absorbs light by measuring the intensity of light across the electromagnetic spectrum’s ultraviolet (UV) and visible (Vis) ranges. The spectrophotometer measures the intensity of light absorbed across the UV and Vis ranges. Light transmitted through the sample is measured and compared to a reference measurement of the incident light source
