PRB21S Bypass Process Refractometer

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.

Features:

– Measures refractive index (nd: 1.3200 to 1.5600) and Brix ( 0 to 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 prisms, made of scratch-proof and chemical-resistant sapphire
– Cleaning via process cleaning processes
– Suitable for process temperatures up to 120 C
– Two interfaces (RS-232, analogue 0/4-20 mA); a PROFIBUS interface is optionally available
– Display for the visual monitoring is also available
