9.6 Probe process refractometer PR-23-GP
The K-Patents Probe process refractometer PR-23-GP is a general industry model for
measuring liquid concentrations in various in-line applications, like chemicals, fibers,
plastics, salts and sodium components. It is typically installed in large pipes and ves-
sels.
