The V-650 is a double-beam spectrophotometer with a photomultiplier tube detector. The high sensitivity of the photomultiplier tube detector enables accurate measurements of low concentration samples. By controlling the high voltage applied to the PM tube, the dynode feedback circuit allows a wider d...
