Atago PAL-68S Potassium Dichromate Refractometer

The PAL-68S is a specialized digital refractometer manufactured by Atago for rapid and precise measurement of potassium dichromate (K₂Cr₂O₇) solution concentration. It is designed for laboratories performing redox titrations, chromating processes, and quality control applications.

The instrument delivers ±0.2% accuracy across the 0.0-15.0% measurement range and provides reliable results across 10.0-40.0°C through automatic temperature compensation. Measurements are completed in approximately 3 seconds using only 2-3 drops (approximately 0.3 mL) of sample, enabling practical rapid process control in demanding applications. The IP65 protection rating ensures durability in field and industrial environments, with operation powered by 2 AAA batteries.

Compared to manual reading methods, the PAL-68S delivers more consistent and reproducible results, providing a reliable measurement solution for processes where concentration control is critical.
