FAQ and solutions in the application of pen pH meter

What are the common problems in the use of pen pH? This article will introduce the common problems and solutions of pen pH in detail: Strictly speaking, temperature compensation should include three parts: temperature compensation of electrode slope, temperature compensation of electrode zero point (including measuring electrode and reference electrode). The temperature compensation set on the pH meter is only the slope item (2.303RT F) of the compensation electrode. Therefore, temperature compensation is not very sufficient for pH meter measurement, nor can it completely eliminate errors caused by temperature. Only because the temperature item of the solution and the zero point temperature item of the electrode cannot be determined, and the error caused is very small, so it can be ignored.
