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.

pH is a measurable parameter between the values of 0 and 14, defining the acidity or alkalinity of a solution. Solutions with a pH = 7 are considered neutral, pH < 7 are considered acidic and pH > 7 ...

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 ...

In addition to pH, ion, voltage and temperature measurement, the combined 781 pH/Ion Meter also offers an automatic stirrer control, a multi-point calibration with up to nine buffers (pH mode), a ...

METTLER TOLEDO announces the launch of NineFocus, its new high-performance, multiparameter benchtop meter system. Designed ...
