Hanna HI99164 Yogurt pH Portable Meter (HACCP)

Hanna HI99164 Yogurt pH Portable Meter – HACCP-Compliant pH Testing for Yogurt and Fermented Dairy Products

The Hanna HI99164 Yogurt pH Portable Meter (HACCP) is a dedicated portable pH and temperature meter designed for yogurt production, fermented dairy products, and HACCP food safety applications. It provides reliable and accurate pH measurements in semi-solid, viscous, and high-protein dairy matrices, helping producers control consistency, shelf-life, and fermentation performance.

Equipped with the HI1414D/50 pre-amplified food-grade pH electrode, the HI99164 is optimized for fast, stable readings in complex dairy environments—making it ideal for both field and lab use in yogurt factories, dairy plants, and quality assurance labs.
