Monitoring pH is crucial in producing consistent, quality yogurt. Yogurt is made by fermentation of milk with live bacterial cultures. Once milk is pasteurized, live culture is added and the mixture of milk and bacteria is incubated. Yogurt producers cease incubation once a specific pH level is reached. By verifying that fermentation continues to a predetermined pH endpoint, yogurt producers can ensure their products remain consistent in terms of flavor, aroma, and texture. The FC2133 pH electrode is rugged and easy to clean with a conical tip and builtin temperature sensor. The open junction design consists of a solid gel interface (viscolene) between the sample and internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it impermeable to clogging after measurements in semi-solid or viscous samples. FC2133 electrode is designed to prevent the typical problems of clogging in viscous liquids, ensuring a fast response and stable reading.
