LabSen® 821 APERA pH Electrode for Milk, Cream, Yogurt and Liquid Food Products

The LabSen® 821 pH Electrode/Probe, engineered with proprietary Swiss sensor technologies and materials, is specifically designed for pH measurement in milk, cream, yogurt, mayonnaise, jam, barbecue sauce, syrup, and other liquid food products. The electrode features an innovative Silver Ion Trap reference system combined with Protelyte electrolyte to prevent protein contamination at the junction point. The unique blue hemispherical glass membrane delivers faster response time, superior reproducibility, and exceptional mechanical and thermal durability (rated to 225°F), making it fundamentally different from fragile traditional glass bulb membranes.
