Binary RuO-CuO Electrodes Outperform RuO Electrodes in Measuring the pH in Food Samples.

Glass electrodes are the only type of pH-sensitive electrodes currently used in the food industry. While widely used, they have several disadvantages, especially in the areas of brittleness and price. Ruthenium(IV) oxide (RuO) pH electrodes are a well-known alternative to conventional glass electrodes, providing improved durability and lower price.
