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 accurate and stable refractive index measurement of difficult food and beverage samples. Designed and manufactured in Japan, the PAL-S belongs to the globally trusted ATAGO PAL™ Series and is specially optimized for testing opaque, fatty, cloudy, dark, and emulsion-based samples that often create inconsistent readings in conventional refractometers.
Equipped with revolutionary Mode S™ Technology, the PAL-S eliminates unstable measurement fluctuations by utilizing an advanced internal stability algorithm. Unlike traditional optical refractometers that rely on subjective interpretation of blurry boundary lines, the PAL-S digitally analyzes sample stability and delivers highly repeatable Brix readings with improved consistency and user confidence.
This compact digital refractometer is ideal for quality control laboratories, dairy processing plants, food manufacturing industries, beverage production facilities, research laboratories, and field testing applications. The instrument performs exceptionally well when analyzing milk, yogurt, condensed milk, soy milk, ice cream mixtures, emulsions, fatty liquids, and dark-colored food products.
The ergonomic one-handed design weighs only 100g and supports hygienic laboratory operation with compliance-friendly construction suitable for HACCP, GMP, and GLP environments. Its rugged IP65-rated waterproof and dust-tight body allows easy washing under running water, simplifying cleaning procedures and improving long-term reliability in demanding industrial settings.
With fast 3-second measurements, Automatic Temperature Compensation (ATC), minimal sample requirement of only 2–3 drops, and external light interference protection, the ATAGO PAL-S provides dependable precision both in laboratory environments and outdoor field applications. The included MAGIC™ adapter further enhances measurement accuracy when testing hot samples by rapidly cooling liquids and minimizing evaporation effects.
