The experimental photometer described was designed as a direct replacement for a Technicon Auto-Analyzer colorimeter in a continuous flow air segmented auto-analysis system. The device was constructed from locally available materials and cost less than $100.00. As built the photometer was very sensitive and was robust and stable enough to be used in a mobile analytical system at sea. This report examines the construction, operation and use of the experimental photometer. An appendix is included which compares the photometer with other similar devices and includes suggestions on the further development of the unit which would give it commercial applications
