A flagship in our product folio is the in-line Process Refractometer-Full Range 2. It is outwardly indistinguishable from the iPR-H2 but the integrated optics and electronics are designed to provide a particularly very wide measuring range from 1.3200 – 1.5300 RI (0-100 Brix). Without major compromises in resolution of 0.01 Brix and accuracy from +/- 0.05 Brix. Thanks to its integrated water cooling system, measurements at process temperatures of up to 150 °C are easily possible.
ID-N° 10970 VariVent connection
ID-N° 10971 TriClamp connection
ID-N° 10972 APV connection
The refractometer iPR FR2 is a stand-alone process sensor with integrated, illuminated display which does not require an external electronic unit. Its special design and electronic configuration make it highly flexible and easy to operate. The programming with Microsoft Windows software is also straightforward. Optional Data Logger is also available. The iPR-FR2 measuring head can be installed in pipes, reactor vessels, mixing tanks, kettles, boiling pans, and evaporators, using different weld-in flanges.
The iPR-FR2 delivers lab quality industrial measurements for a range of industries, including food and beverage, chemical, pharmaceutical, medical, and packaging industries.
Applications include condensate measurement, control of disinfectants for packaging, purity control for pharmaceuticals, liquid-liquid extraction and many more.
This process refractometer lasts in the roughest conditions while delivering precise and reliable industrial measurements. With a certified IP69K protection class tested by the reliable German standardization institution TÜV, it can simultaneously withstand aggressive chemicals and high temperatures.
For flexibility in use, the product has two analog and two digital interfaces so that you can fully and easily integrate the measuring head into your production process.
A selection of cost-effective process flanges, the VariVent, and other connection devices accompany the iPR-H3, with which the instrument is technically easy to implement.
With the pig pipe addition, the iPR-FR2 allows for Cleaning In Place (CIP).
