How to Improve the Accuracy of Pure Water pH Measurements:

For better pH measurement of pure water, we recommend the following steps:

1: Choose a Professional Pure Water Electrode: For instance, our imported P15 glass pH electrode is a great option. If budget constraints are a concern, make sure to select a fast-flow, refillable pH electrode, such as the E200-BNC plastic electrode.

2: Use a Small Sample Volume: Measuring large volumes or flowing liquids may result in longer stabilization times.

3: Add a Trace Amount of Potassium Chloride: This will enhance the ionic strength of the sample and speed up response time. However, ensure that high-purity potassium chloride is used.

4: Use Clean Containers: Avoid contamination by using clean containers.

5: Perform Sealed Measurements: This helps to reduce the impact of carbon dioxide from the air.
