This letter, written while Arnold Beckman was on a multi-city trip promoting his pH meter, concerns strategies for marketing the instruments and concern about the friction between a salesman and distributor.
Arnold Beckman invented his first pH meter in 1934 at the request of a chemist from the California citrus industry, who needed an accurate way to measure the acidity of his product. The resulting instrument kicked off rapid development not only of Beckman Instruments, Inc. but also of the electronic scientific instrument industry.
