The IPR FR 2(Full range) process refractometers continously measures the refractive index , temperature and BRIX of liquids in a process vessel or pipe.. The measurement is independent of light intensity from the light emitting diode (LED) and is free of signal drift, thus providing high precision and better process control. Colour, turbidity, undissolved particles or gas bubbles do not affect the measurement.

The iPR FR 2 is an index/concentration/temperature, transmitter with integrated electronics. It includes an illuminated LCD display for local monitoring. Its special design and electronic configuration makes it highly adaptable to a variety of process scenarios. The stainless steel measuring head is resistant against chemicals, and is suitable for mounting on an aseptic flange for food products. Cleaning in Place (CIP) and pipe pigs can be used as the measuring face is flush with the pipe wall. The unit can be installed in pipes, reactor vessels, mixing tanks, kettles, boiling pans and evaporators, using different weld-in flanges and connectors. The refractometer is set up via a PC link with the included software. Once initialised the iPR functions as a stand alone transmitter passing its data via relays, analog and digital links to your process data monitoring systems.
