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” ...

Although it can feel like it’s all up to the luck of the draw, to successfully grow a garden, it takes a little more than chance. For optimal growth, it’s important to find the best location for sun ...

In this post, Mike walks through how to calibrate a pH meter for homebrewing. Specifically, he demonstrates the process using the Milwaukee MW102 pH meter, the same meter he used during his mash pH ...

Place the pH probe in each standard and record the output (in millivolts) for each standard. Enter the values in your calculator and determine the slope of the line. Figure 2 shows a typical plot of ...

pH meters are used to determine the pH of a water sample or solution. There are four pH meters in the engineering laboratories. pH meters use electrodes to determine the difference in electrical ...

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 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 ...

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 ...

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 ...
