Prominent among the characteristics responsible for the outstanding performance of the Evelyn Photoelectric Colorimeter is its notable simplicity of design. By the reduction of mechanical and electrical elements to the minimum consistent with sound photometric analysis and by unsparing effort to achieve in these few elements the ultimate in long-term reliability, there is realized in this instrument an uncommon degree of dependability. Proven by practical application during the past ten years in nearly every phase of chemical activity, the Evelyn Colorimeter is thoroughly established as a standard laboratory instrument for both research and routine control work. A detailed discussion of the design of this invaluable analytical tool is available on request. Described in Bulletin 460
