The reprinted article, originally published in Bakers Digest, was written by employees of the Fleischmann Laboratories and featured photographs of Beckman pH meters.
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.
