In-line process digital refractometer iPR FR² with extremely short reaction time for continuous measurement and real-time process control with an analogue data output. It is characterized by minimal size and weight and has an excellent price-performance ratio.

The fully automatic process digital refractometer IPR Basic3 continuously measures the refractive index and thus the concentration of solids in solutions or the mixing ratios of binary or quasi-binary liquid mixtures. The measurement is independent of process air, turbidity, colour of the process solution and the light intensity of the LED.
