The inline process refractometers PR21S and PR21S-T are installed in pipelines of production facilities in order to control and regulate the concentration, mixing and fermentation processes. Thanks to the standardised connections, the measurement devices can be easily installed in pipelines. The measuring chamber is made of stainless steel, the measurement prism consists of scratch-resistant and especially chemical-resistant sapphire and is designed to prevent solids from sticking.
The process refractometer is the ideal solution for the chemical, petrochemical, automotive, aviation, metal processing, food, sugar, beverage, paper industries as well as wastewater control.
