Atago PAL-39S Hydrogen Peroxide Refractometer – H₂O₂ Concentration Analyzer

Atago PAL-39S is a digital handheld refractometer specifically designed for rapid and accurate measurement of hydrogen peroxide (H₂O₂) disinfectant solution concentration. Using just 2-3 drops of sample, it delivers results in the 0.0-50.0% range within approximately 3 seconds, providing fast quality control for medical, industrial sterilization, and disinfection processes.

The instrument features IP65 protection rating, enabling safe operation in wet and humid laboratory environments. Powered by 2 x AAA alkaline batteries and weighing only 100 g, the compact design ensures excellent portability for field use. Results are displayed directly in percentage (%) on the LCD screen. Note: The unit does not feature automatic temperature compensation; consistent temperature conditions are recommended for reproducible measurements.

With ±0.6% accuracy and 0.2% resolution, the PAL-39S delivers reliable results for disinfectant manufacturing, quality control laboratories, and sterilization applications. Its straightforward operation principle and rapid measurement time make it user-friendly for operators without specialized technical training.
