Vaisala Process Refractometer PR-43-G – Chemical

Key Benefits
Designed for harsh environments

Vaisala (formerly K-Patents Process Instruments) Process refractometer PR-43-G is designed for harsh environments that can be corrosive, abrasive, subject to extreme temperatures, pressures, vibration or contamination, humidity and dust, or any combinations of these factors. Selection of different IP codes (IEC 60529) and NEMA ratings are available for the refractometer and user interface that withstand various harsh conditions also when the equipment needs to be used outdoors.

Vaisala Probe Process Refractometer PR-43-GP
For general industry pipe and vessel installations. Available in 2, 3 and 4-inch flange and 3 inch Sandvik L coupling process connections and a variety of flow cells for pipe sizes of 1 inch and larger. Selectable multichannel, compact or a web-based user interface options. Special wetted parts materials and intrinsically safe and hazardous area certification provided.

Vaisala  Compact Process Refractometer PR-43-GC
For general industry small pipeline and bypass line installations. Available in 2 inch and 2.5 inch process connections and via reducing ferrule in 1.5-inch process connection. Installed in the process either directly in a pipe elbow by an L coupling connection or in a straight pipe via a Wafer flow cell or a Pipe flow cell. Selectable multichannel, compact or a web-based user interface options. Special wetted parts materials and intrinsically safe and hazardous area certification provided.

Vaisala (formerly K-Patents Process Instruments) general type process refractometer PR-43-G is made to last and is an ideal all-round instrument for measuring the liquid concentration and density in a wide range of industrial applications. The PR-43-G masters highly accurate measuring technology in demanding process control applications where conventional density equipment may struggle due to undissolved solids or bubbles in the process stream.

The refractometer system consists of a compact or probe refractometer and a graphical user interface. The refractometer is a stand-alone device capable of operating independently or together with a physical user interface. It has a measurement range of 0 to 100 % and it provides an Ethernet or 4–20 mA output signal proportional to the temperature-compensated concentration value for real-time process control. Different user interface options range from a rugged, multichannel, industrial computer to a compact lightweight and a web-based version which allow the user to select the most preferred way to access and use the refractometer measurement and diagnostics data.

The refractometer built-in web server and instrument homepage enable remote monitoring, configuring and diagnostics via an Ethernet connection. Every PR-43-G Refractometer also provides an mA output signal for control purposes. Special wetted parts materials and hazardous area certifications are available.




Manufacturer info

K-Patents is part of Vaisala’s Industrial Measurements Business Area.

Vaisala, a global leader in weather, environmental, and industrial measurements, has finalized the merger of the K-Patents Group, a pioneer in in-line liquid measurements for industrial applications.

Following the completion of the acquisition, K-Patents Oy and Janesko Oy, K-Patents’ research and development organization, have ceased to exist and operations have moved to Vaisala.
