Atago PAL-BX|ACID1 Master Kit – Citrus Brix-Acid Analyzer

The PAL-BX|ACID1 Master Kit is a hybrid handheld analyzer manufactured by ATAGO that combines sugar and acidity measurement for citrus fruits such as oranges, lemons, mandarins, and grapefruits in a single device. Brix value is measured via light refraction (refractometry), while acidity is determined using electrical conductivity principles; this eliminates the need for traditional acid-base titration, reagents, glassware, and complex disposal procedures.

The analyzer measures 0.0-90.0% Brix and two acidity ranges (0.10-4.00% low, 2.50-8.80% high), accommodating both sweet and acidic citrus varieties. Measurement is completed in approximately 3 seconds by placing the sample on the stage and pressing START, with automatic temperature compensation ensuring reliable results across a 10-40°C operating range.

Its compact (55×31×109 mm) and lightweight (100 g) design with IP65 protection rating enables convenient operation under field conditions. Powered by 2 × AAA batteries. The Master Kit package includes essential accessories for measurement, enabling rapid deployment in quality control, harvest monitoring, and research and development applications.
