Note: This tool does not provide an accurate or consistent pH test reading in distilled or deionized water. In fact, demineralized distilled water does not contain enough ions for the electrodes to function properly. To measure the pH of distilled or deionized water, the user must use a special electrode. Do not store the probe in distilled or deionized water as this may damage the glass membrane of the pH probe. Use only distilled water to clean the pH probe.
