Atago PAL-53S Copper Sulfate Refractometer – Agriculture and Industrial Solutions

The PAL-53S is a digital handheld refractometer developed by Atago for rapid and practical measurement of copper sulfate solution concentrations. It is engineered for agricultural operations preparing fungicide mixtures and industrial facilities utilizing copper sulfate in their processes.

The instrument delivers results within seconds using only 2-3 drops of sample, enabling field-based rapid quality control compared to time-consuming laboratory methods such as titration. With IP65 protection rating, it resists dust and water splash, making it suitable for field and facility conditions. Note that the unit lacks automatic temperature compensation; therefore, ambient temperature variations should be considered during measurements.

The PAL-53S offers a practical solution for seasonal field applications and in-facility rapid verification checks, combining compact design with portability for professional use across agricultural and industrial environments.
