ATAGO® PRM‑TANKα(FLN) Process Refractometer

ATAGO® PRM‑TANKα(FLN) Process Refractometer

The ATAGO® PRM‑TANKα(FLN) is a process refractometer designed with a newly engineered detection unit that mounts directly onto the wall of a vessel. This configuration makes it ideal for distillers, condensers, blenders, fermenters, extractors, filtration tanks, and other vessel‑based processing systems. The flat sample stage prevents buildup of solids and residue, keeping the prism clean and ensuring stable long‑term measurement performance.

Key Features

• Wall‑mounted detection unit for vessel‑based processing
• Flat sample stage prevents buildup and keeps prism clean
• Continuous measurement of refractive index, Brix, concentration, and temperature
• High‑accuracy optical system suitable for industrial process control
• Selectable resolution for refractive index and Brix
• RS‑232C and DC 4–20 mA output for integration with control systems
• High/low alarm output via open‑collector signal
• Temperature compensation from 5.0 to 100.0°C
• Long cable length options up to 200 m for flexible installation
