Abstract
An infrared-light-emitting-diode-based photometer has been developed f or use in measuring copper concentrations in hard-chromium and other p lating baths. This device provides accuracy comparable to that of more sophisticated techniques, is easy to operate, requires no sample prep aration, creates no waste, and can be assembled from a small number of simple and inexpensive components.
