ATAGO® PRM‑2000α In‑Line Refractometer

ATAGO® PRM‑2000α In‑Line Refractometer

The ATAGO® PRM‑2000α is a high‑precision in‑line refractometer designed for low‑sugar beverages, cleaning solutions, and other applications requiring extremely accurate measurement in the 0–20% Brix range. It offers exceptional accuracy of ±0.007% up to Brix 2.000% and ±0.050% from Brix 2.001% to 20.000%, making it ideal for processes where small concentration changes must be detected reliably.

Key Features

• High‑accuracy Brix measurement for low‑sugar and low‑concentration applications
• Wide refractive index range suitable for various industrial fluids
• Continuous in‑line measurement of refractive index, Brix, concentration, and temperature
• LED light source (D‑line approximation) for stable optical performance
• IP67 protection for both detection and display sections
• 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 to 90°C
• CIP/SIP resistance up to 165°C for 30 minutes
