Inline Process Refractometer PIOX R721 – Hygienic Design Variant

Process Refractometer for Hygienic Environments

In many processes of the food and beverages as well as in the pharmaceutical industries real-time inline concentration measurement is the key to continuous quality control and efficient production. With its process refractometer PIOX R721, FLEXIM offers for this purpose the most powerful measuring instrument of its kind.

Whether the degree of ° Brix needs to be monitored during soft and fruit drink production or concentration levels of ascorbic and cetogulon acid during Vitamin C manufacturing have to be supervised, PIOX R721 outputs the desired values with an accuracy of 0.1%.

PIOX R721 is highly hygienic by itself. With its stainless steel housing, the sapphire prism and completely engineered with no allowance for dead spaces, potential bacterial contamination can be ruled out at any time.

PIOX R721 can be integrated into the process via Varivent or Tri-clamp compatible flanges.


  • Highly accurate, reliable and hygienic real-time concentration measurement solution (° Brix, Oechsle, Plato, sugar content and more)
  • No measurement drift due to potential plate out as often indicated when employing conventional critical angle refractometers
  • Quality assurance due to real time product monitoring - costly laboratory testing becomes obsolete
