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” ...

Understanding the nature of pH has bedeviled beginning (and not-so-beginning) chemistry students for nearly as long as chemistry has had students. It all seems so arbitrary, being the base-10 log of ...

pH meters are an essential part of many laboratories. pH can affect microbial growth and chemical reactions, pH meters must be calibrated regularly. pH meters consist of either distinct reference and ...

While there are a variety of other variables and protocols to be followed to ensure our food supply remains safe, a basic understanding of pH and how it is measured is crucial to food production.

Jenco 6175 benchtop pH meter is the successor of the popular 6173 benchtop pH meter. While the large LCD display and easy of use remains firmly in place, model 6175 now offers 0.1 mV resolution for ...

The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass. The device is termed as pHduino which can operate by ...
