Inline Process Refractometer

在线过程折光仪

Beverage, sugar, brewing and chemical plants control concentration continuously with a refractometer mounted in the pipe. This inline sensor uses a sapphire prism, measuring 1.3200–1.5000 nD or 0–85% Brix at ±0.0002 nD. It tolerates −20 to 150 °C process temperature and 1.0 MPa pressure. Outputs are 4–20 mA and RS-485/Modbus in an IP67 housing.
