Abstract
The present invention concerns a new optical photometry system for on-line analysis of industrial fluid streams. The invention is a general purpose optical photometer, capable of absorption, fluorescence and reflectance measurements at single wavelengths in the ultraviolet, visible and near infrared spectral ranges. Light signals generated by the light source are carried between a central photometric console and remote analysis sites by fiber optic cables. The return light signals are compared with a standard to make the desired analysis.
