Bypass process refractometer PRB21S
Accurate results for automatic and continuous process control
The bypass 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 1.3200-1.5600 and 0-95 %Brix
- Measurement intervals approx. 10 seconds
- Automatic temperature compensation (%Brix and freely definable for customer-specific products
- Integrated sensor for temperature monitoring
- User-defined scale
- Stainless steel measurement chamber that meets all the requirements of the food and pharmaceutical industry, CIP capable
- Sample prism, made of scratch-proof and chemicalresistant sapphire
- Cleaning manually or via customer process cleaning
- Suitable for process temperatures up to 60 °C
- Two interfaces (RS-232, analogue 0/4-20 mA)
- A display for the visual monitoring is also available
