iPR HR² Inline Process High-Resolution Refractometer
The iPr-HR2 is perfect for all applications where measurements need to be as precise as laboratory testing with its extremely precise process sensor delivering the highest resolution: up to 5 x 10-6 RI (2 x 103 Brix), precision up to +/- 4 x 10-6 RI (+/- 2 x 10-2 Brix). With a special water cooling system, the iPR-HR2 allows measuring in hot process environments and cleaning in place (CIP).
This device helps you to monitor and control your production process. Similar to a laboratory refractometer the 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 make it highly flexible and very easy to operate. Connecting and programming the device using Windows software is also very simple. An optional data logger is available.
The iPR HR² (High Resolution) is a fully automated high-resolution process refractometer that continuously measures the refractive index and thus, the concentration of a binary or quasi-binary liquid mixture.
The iPR HR² is specifically developed for the control of liquids with a very low solid content (e.g. light drinks) as their RI determination requires high resolution and precision.
The stainless steel measuring head is:
- IP69K protection class-tested by TÜV
- Chemical resistant
- Food safe
- CIP (clean in place) capability
The iPR HR² measuring head can be installed in pipes, reactor vessels, mixing tanks, kettles, boiling pans, and evaporators using different weld-in flanges. The Schmidt + Haensch VariVent Process Adaptor is recommended for pipeline connectivity as it allows for the attachment of a cleaning device for units that require cleaning of the sensor face. An optional cleaning nozzle or an ultrasonic cleaning device is also available.
