K-Patents Sanitary Compact Refractometer PR-23-AC provides accurate means for measuring Brix and liquid concentrations in hygienic installations and in small pipe line sizes of 2.5 inch and smaller.
The PR-23-AC sensor is installed in the pipe bend. It is angle mounted in the outer corner of the pipe bend directly or through a flow cell, a Sanitary clamp or a Varivent® connection. This way the best flow conditions and self-cleaning effect can be achieved.
The measurement range covers 0-100 Brix. The accuracy is ± 0.1 Brix and the measurement is automatically temperature compensated. Low and high concentration alarms can be configured. Because of the digital sensing technology, even large amounts of suspended solids, bubbles or color changes do not affect the measurement or the accuracy.
Each sensor is provided with a calibration certificate comparing a set of standard liquids to the actual sensor output. The calibration and accuracy can be verified on-site with the certified Refractive Index liquids and K-Patents documented procedure.
