Applications
Process refractometer PRB21 was developed for reliable process monitoring and control as well as for quality and quantity control in following industries:
- Pulp and paper industry
- Chemical and petrochemical industry
- Beverage industry
- Food industry
- Sugar and sweetener industry
- Textile industry
- Metal working industry
- Wastewater management
Our new PRB21 measures the refractive index with high accuracy and enables sophisticated process monitoring. Measurements are not influenced by color or turbidity. The PRB21 provides a temperature-compensated reading to meet your process requirements. It covers a high range of applications in the food-, sugar-, beverage-, chemical-, textile-, paper-, metalworking-, and petrochemical industries. The instrument is also perfect for waste-water control and a number of other quality inspections.
