SCHMIDT + HAENSCH is proud to present the in-Line Process Refractometer High Resulution2 model. This inline refractometer is perfect for all applications where a measuring needs to be as precise as laboratory testing. The iPR HR2 is unrivaled in accuracy and can most certainly be claimed the world’s most precise process sensor.
With a special water cooling system, the iPR HR2 not only allows measuring in hot process environments and cleaning in place (CIP) – it also and ensures reliable measurements throughout its long product life span.
ID-N° 10990 VariVent Connection
ID-N° 10991 TriClamp Connection
ID-N° 10992 APV Connection
This device helps you to perfectly monitor and control your production process. Similar to laboratory refractometers iPR HR2 is a stand alone process sensor with an integrated, illuminated display, which does not require an external electronic unit. Its special design and electronic configuration makes it highly flexible and very easy to operate. Connecting and programming the device using Windows software is also very simple. Optionally, a data logger is available.
This device delivers the highest resolution on the worldwide market: up to 5 x 10-6 RI (2 x 10-3 Brix), precision up to +/- 4 x 10-5 RI (+/- 2 x 10-2 Brix).
The iPR HR2 delivers lab quality industrial measurements for food and beverage, chemical, and packaging industries, as well as for the pharmaceutical and medical industries.
Applications include condensate measurement, control of disinfectants for packaging, purity control for pharmaceuticals, liquid-liquid extraction and many more.
This process refractometer is robust in the roughest conditions while being the world’s most precise process sensor. With a certified IP69K protection class tested by the reliable German standardization institution TÜV, it can simultaneously withstand aggressive chemicals and high temperatures. The iPR HR2 guarantees high resolution and high precision in even the toughest conditions.
For flexibility in use, the product has two analog and two digital interfaces so that the measuring head can be fully and easily integrated into the production process.
A selection of cost-effective process flanges, the VariVent, and other connection devices accompany the iPR H2, with which the instrument is technically easy to implement.
With the pig pipe addition, the iPR HR2 allows for Cleaning In Place (CIP).
