ATAGO PAL-S Digital Handheld Refractometer – Advanced Mode S™ Brix Measurement Technology
The ATAGO PAL-S Digital Handheld Refractometer is a highly advanced portable Brix meter engineered for stable, repeatable, and highly accurate measurement of difficult food and beverage samples. Designed and manufactured in Japan, the PAL-S belongs to the globally trusted ATAGO PAL™ Series and incorporates innovative Mode S™ Technology, specifically developed to minimize unstable readings commonly encountered with opaque, cloudy, fatty, dark, or emulsion-based samples.
Unlike conventional handheld refractometers that often produce fluctuating boundary lines and inconsistent readings, the PAL-S digitally analyzes measurement stability using an intelligent internal algorithm. This allows laboratories, dairy processors, food manufacturers, beverage industries, and quality control departments to obtain dependable Brix readings with improved repeatability and reduced operator interpretation error.
The PAL-S refractometer is particularly suitable for measuring milk, yogurt, soy milk, ice cream, condensed milk, emulsions, dairy products, and high-viscosity food samples. Its fast measurement speed delivers accurate Brix values within approximately three seconds using only 2–3 drops of sample, significantly improving laboratory productivity and process efficiency.
Engineered for field and laboratory environments, the instrument features a compact ergonomic design weighing only 100g for convenient one-handed operation. Its IP65-rated waterproof and dust-tight construction supports hygienic operation and allows the sample stage to be safely rinsed under running water. The hygienic structure also aligns with HACCP, GMP, and GLP operational requirements for food safety and laboratory quality assurance.
The integrated Automatic Temperature Compensation (ATC) system ensures accurate Brix measurement across a broad temperature range of 10°C to 100°C, even when testing hot food products. For enhanced hot sample measurement stability, the included MAGIC™ adaptor rapidly cools high-temperature samples and reduces evaporation effects.
Additional reliability is provided through ATAGO’s patented External Light Interference (ELI) technology, which minimizes inaccurate measurements caused by intense outdoor or direct lighting conditions. Combining precision optics, intelligent stability analysis, rapid digital measurement, and exceptional portability, the ATAGO PAL-S offers an ideal solution for modern food quality control, dairy testing, beverage analysis, and industrial laboratory applications.
