Description
Technical data

A.KRÜSS Optronic Process Refractometer PR 21
Complete quality control!

Process refractometers are built directly into pipework and boilers or operated in the bypass. They are ideal for process monitoring, control and product separation in a variety of industries (chemicals, beverages, food and sugar). Why use Refractometers in pipelines? The monitoring of refractive index is a popular method of inline quality control in many process industries, including pulp and paper, food and beverage, chemical and pharmaceutical, and wastewater. It provides real-time data for quality control and Good Manufacturing Practice (GMP), and can be used to monitor qualities such as concentration of a solution, density of a fluid, or % Brix. An inline process refractometer is installed directly into pipework or a boiler, with standard connections for easy assembly. The alternative bypass process refractometer analyses a stream of fluid drawn off the main process run.

PR21 Series Process Refractometer
As no bypass is necessary, it is much simpler to install the process refractometer in a pipeline or tank. Standard connections enable the process refractometer to be assembled quickly and easily. Depending on diameter, a T-piece is inserted into the pipeline or an adapter welded on, as with the tank.

Three interfaces are available for this unit: Analogue 0/4-20 mA, Ethernet, or PROFIBUS.
