Then, connect the meter to the output of the circuit and adjust the Y-intercept potentiometer until the circuit yields the pH of the standard you use. (For example, a pH of 10.1 reads 0.101V.) To ...

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 ...

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” ...

The requirements set forth in the above referenced standard include using a pH meter with a resolution of 0.1 pH units. Most small pocket testers, handheld meters, and benchtop meters will offer ...

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 ...
