Fully Automated Process Refractometer
The automatically operating process refractometers iPR HR² (High Resolution) measure the refractive index continuously and thus, the concentration of a binary or quasi-binary liquid mixture. They are especially develops for the check of liquids with very low solid concentrations (e.g., Light drinks). iPR HR² own a high resolution and precision.
The refractometer iPR HR² is a stand alone process sensor with integrated, iluminated display, which does not require an external electronic unit. Its special design and electronic configuration makes it highly flexible and very easy to operate. The programming with a Windows software is also very easy.
The stainless steel measuring head is:
- IP69K protection class tested by TÜV!
- against chemicals
- suiting food regulations
- CIP conform (pipe pig use possible)
The iPR measuring head can be installed in pipes, reactor vessels, mixing tanks, kettles, boiling pans and evaporators, using different weld-in flanges.
- Permanent real-time concentration measurement
- Highest resolution and precision
- For applications with very low solid concentrations
- Stand-alone sensor with integrated electronic
- Configurable digital switches
