UR62 - Refractometric wine analyzer

The UR62 is a digital refractometric probe built for direct in-line or in-tank installation, continuously measuring and displaying product concentration in Brix, nD or percentage. Thanks to its optical measuring principle, the analyzer maintains stable accuracy over time without requiring recalibration against laboratory readings once configured. Its rugged 316 stainless steel construction with IP67 protection suits demanding, aggressive process environments, while an RS485 interface and 4-20 mA output allow easy setup and integration into plant control systems.
