	Brochure Product manual
K-Patents Process Refractometer PR-01-S is a heavy-duty instrument for in-line concentration measurement of black liquor and green liquor. The unique digital measurement principle warrants high accuracy and repeatability even in very harsh process conditions. Gas bubbles, particles or colour of the medium do not affect the measurement. The process temperature is measured and it is automatically compensated. The key features: Rugged sensor for demanding applications. Easy installation directly in the pipe or vessel through a wide range of process connections. Refractive Index measurement ranges: low range 1.320 – 1.460 R.I. or high range 1.380 – 1.530 R.I. Process temperature range: -20°C - 150°C (-4° – 300°F). Completely digital design: no drift, no re-calibration, no maintenance. Accurate temperature measurement and automatic temperature compensation. Wetted parts materials are stainless steel 316L, Teflon® , Spinel, and Kalrez®. Excellent chemical and mechanical resistance. Special alloys available on request. Easy to operate with clear multi-diagnostic messages and programmable alarms. K-Patents Process Refractometer PR-01-S sensor can be equipped with Isolation Valve and Retraction device HIMP which allows retraction and insertion of the sensor probe without interrupting the process stream.
