Process Refractometer Model PR-23-GP

A Process Refractometer for Concentration Measurement of Liquids

Process Refractometer PR-23-GP provides truly accurate means for measuring liquid concentrations and Brix in various process applications. PR-23-GP determines the concentration of dissolved solids by making an optical measurement of a solution’s re­fractive index. The measurement accuracy is not influenced by particles, bubbles, sugar crystals, seeds, fibres, colour or temperature changes in the process medium. PR-23-GP does not require any recalibration or regular maintenance.

PR-23-GP includes an Ethernet based communications solution which allows connection to computer networks (LAN) and to the Internet. Real-time measurement data and diagnostic information may be obtained through this interface, and this makes it also a valuable service tool for parameter changes and software updates. Only a cross-over cable and data acquisition software are needed for collecting the data from a PR-23 refractometer. The communication is built on standard protocols (UDP/IP) and K-Patents offers ready-to-install software for data acquisition.
