Atago PAL-66S Digital Potassium Oxalate Refractometer

The PAL-66S is a specialized digital handheld refractometer developed by Atago with a dedicated scale for rapid and precise measurement of potassium oxalate (K₂C₂O₄·H₂O) solution concentration. Designed for analytical chemistry laboratories and industrial processes utilizing potassium oxalate for concentration monitoring and process optimization.

The instrument operates within a 0.0-10.0% (w/w) measurement range with 0.1% resolution and provides ±0.2% accuracy. Integrated automatic temperature compensation (ATC) delivers reliable results independent of ambient conditions between 10-40°C. Single-drop sampling with automatic measurement completion in 3 seconds eliminates manual calculation time, enhancing productivity in repetitive measurement workflows. The metal housing with IP65 protection rating enables operation in both laboratory and industrial environments.

Low sample repeatability variance (RSD ≤0.2%, n=10) ensures consistent measurement results across sequential analyses. The simplified operation and rapid measurement capability deliver significant time and reagent savings compared to conventional titrimetric or gravimetric methodologies.
