PR53SD Safe-Drive Process Refractometer
This refractometer is designed for measurements where safety is important in pulp mills, such as the concentration of combustion liquids.
basic information
The Vaisala Polaris PR53SD process refractometer is designed to meet the most demanding process conditions in the pulp industry, measuring the concentrations of black liquor, green liquor, brown raw material washing, and other liquids in fiber and chemical recovery lines. The PR53SD process refractometer is at the core of our stable and reliable measurements, and the process refractometer can be maintained without stopping the process, minimizing measurement downtime. Therefore, it is suitable for critical and safe measurements in pulp mills. The state-of-the-art design of the SAFE-DRIVE retractor system enhances safety by integrating the process refractometer and retractor into a single simple system. This prevents errors due to inattention during use and ensures that the shut-off valve is securely closed before removing the measuring instrument. The system is easy to operate, allowing for the insertion and removal of the process refractometer into and from a pressurized process line with just a few steps while keeping operations fully running.
