Now--New Beckman pH Electrodes
The advertisement touts the features of Beckman glass electrodes and the company's position in the instrumentation field.
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.
