Beckman Model 72 Ph Meter With Buffer Solution Science History While a professor at california institute of technology, he founded beckman instruments based on his 1934 invention of the ph meter, a device for measuring acidity (and alkalinity), later considered to have "revolutionized the study of chemistry and biology". [1]. When arnold beckman, a professor of analytical chemistry at the california institute of technology, was asked to devise a way to measure acidity in citrus fruit, the resulting “acidometer” revolutionized chemical instrumentation.
Arnold O Beckman Science History Institute In 1934 beckman invented the first commercially successful electronic ph meter and then went on to found an international scientific instruments company. Arnold o. beckman was a caltech alumnus (phd ‘28), former faculty member, and trustee. he was also the founder of beckman instruments (now beckman coulter), a company that began with beckman’s invention of the ph meter, now one of the most widely used pieces of laboratory equipment in the world. Beckman instruments, inc., founded by dr. arnold o. beckman in 1935, entered the laboratory market with the world’s first ph meter, an electronic instrument used to measure ph (acidity or alkalinity). the company became a publicly traded corporation in 1952. Beckman responded by inventing the “acidimeter.” this device not only solved his friend’s specific problem; it became the world’s first ph (acidity alkalinity) meter and was the basis upon which, in 1935, beckman founded beckman instruments, inc. (now beckman coulter).

Beckman instruments continued to make ph meters, but also began producing other types of scientific instrumentation. the ph meter remains one of the most common pieces of laboratory equipment, used in research labs, clinical labs, and production facilities worldwide. On the american west coast, our company’s story begins with a groundbreaking, yet simple, invention by dr. arnold o. beckman in the early 1930s. he found a solution for determining the precise measurement of ph in lemon juice—the acidimeter, or ph meter. National inventors hall of fame inductee arnold beckman founded beckman instruments, inc., in 1935 with the development and invention of the ph meter. When asked about an instrument suitable for testing citrus fruit, arnold beckman, a young chemist at the california institute of technology, designed one with glass electrodes, and showed a prototype at the american chemical society meeting in 1935.
