Atago PAL-43S Magnesium Chloride Refractometer – De-icing Solution and Tofu Production Analysis

The PAL-43S is a specialized digital refractometer manufactured by Atago for measuring the concentration of magnesium chloride-based de-icing/anti-icing solutions and tofu production coagulant solutions. With a measurement range of 0.0-30.0% MgCl₂ and accuracy of ±0.2%, it delivers results in approximately 3 seconds using only 2-3 sample drops.

The instrument is engineered for field technicians, municipal road maintenance departments, and tofu manufacturers who require rapid and reliable concentration control in outdoor environments. Its IP65 protection rating ensures reliable operation under harsh field conditions including water, dust, and moisture exposure; automatic temperature compensation maintains measurement consistency across varying ambient conditions.

Compact dimensions (5.5 × 3.1 × 10.9 cm) and operation on 2 x AAA alkaline batteries make it a practical field tool for out-of-laboratory applications. In de-icing applications, accurate MgCl₂ concentration measurement ensures optimal cost-effectiveness and performance, while in tofu production, precise coagulant concentration directly impacts product quality and consistency.
