PR-43-P Pharma Process Refractometer
Brand: K-Patents Process Instruments
K-Patents has applied its expertise to developing the unique and innovative Pharma process refractometer PR-43-P to measure, refine, manage and indicate liquid concentration or density and diagnostic information.
The Pharma refractometer PR-43-P is designed to meet pharmaceutical industry standards and guidelines including PAT, GMP, CIP/SIP, 21 CFR Part 11 and validation.
The Pharma PR-43-P system consists of a compact process refractometer and a graphical user interface. The PR-43-P has a measurement range of 0 to 100 Brix and provides an Ethernet or 4–20 mA output signal proportional to the temperature-compensated concentration value for real-time process control.
The user can choose between a rugged, multichannel, industrial computer or a compact light-weight user interface.
The PR-43-P Refractometer has a built-in web server with an instrument homepage. The homepage enables the configuration, monitoring, verification and diagnosis of the refractometer via an Ethernet connection.
Every PR-43-A Refractometer also generates an mA output signal for control purposes. The PR-43-P refractometer needs no recalibration or regular maintenance. Furthermore, the calibration of each refractometer can be verified using standard refractive index liquids and a built-in verification procedure.
