When someone mentions calibration, engineers probably think of voltage, frequency, and other fundamental electrical measurements. Light measurements may not come to mind unless these engineers work ...
A pH meter measures a pH or the acidity/alkalinity of substances. Most pH meters rely on a glass electrode that measures the number of hydrogen ions in the solution. Usually, pH meters need to be ...
Let's say you're performing a critical calibration or measurement in a bridge configuration. You have your choice of a high-resolution digital multimeter and an analog nullmeter with nanovolt ...
