The Atline process refractometer PRB21S are installed in tanks or boilers using tube connections for the continuous monitoring and control of the concentration of liquids. The sample flows via the bypass into the measurement chamber made of stainless steel. The measurement prism consists of scratch-resistant sapphire and is resistant against solvents and acids. • Determination of refractive index in the range of nD 1.3200-1.6000 and 0-95 %Brix • Measurement intervals from 3 to 60 seconds selectable • Automatic temperature compensation (%Brix and freely definable for customer-specific products • Integrated sensor for temperature monitoring • Brix scale (sucrose, glucose, fructose and invert sugar) • Stainless steel measurement chamber that meets all the requirements of the food and pharmaceutical industry, CIP/SIP capable • Sample prism, made of scratch-proof and chemicalresistant sapphire • Cleaning manually or via internal process cleaning • Suitable for process temperatures up to 60 °C • Two interfaces (RS-232, analogue 0/4-20 mA); a PROFIBUS interface is optionally available • A display for the visual monitoring is also available • Compliance with global standards
