Process Refractometer PR-43-AC

Sanitary Process Refractometer PR-43-AC

The unique and innovative Sanitary refractometer PR-43-AC was designed for sanitary applications in biotechnology, food & beverage and pharmaceutical industry. It consists of a stand-alone operating refractometer, with the optional graphical user interfaces. The refractometer has a temperature compensated measurement range of 0 to 100 Brix and provides an Ethernet or 4–20 mA output signal for real-time process control.

The PR-43-AC refractometer is designed to meet the needs of hygienic installations in small pipe line sizes of 2.5 inch and smaller. The PR-43-AC refractometer is installed in the outer corner of the pipe bend directly or through an optional flow cell with a Sanitary clamp or a Varivent connection. This way the best flow conditions and self-cleaning effect can be achieved. Optional user interfaces consist of a rugged multichannel industrial computer, or a compact light-weight computer. The user interface of the refractometer can be installed locally in the field, remotely in the control room or in both locations by connecting several user interfaces in a network.

The refractometer is factory calibrated and does not require any recalibration or regular maintenance. Furthermore, the calibration of each refractometer can be verified using standard refractive index liquids.

Characters in the product name indicate particular parameters of the instrument.
