Atago PAL-70S Potassium Phosphate Refractometer

The Atago PAL-70S is a specialized digital refractometer designed for fast, accurate measurement of potassium phosphate solution concentration. It is an ideal field/laboratory instrument for users engaged in fertilizer production, agricultural solution preparation, and hydroponic system monitoring.

The instrument operates in a 0.0–15.0% measurement range with ±0.3% accuracy. Only 2–3 drops of sample are required, and measurement is completed in approximately 3 seconds. Automatic Temperature Compensation (ATC) ensures consistent results across varying ambient temperatures. The IP65 water-resistant housing enables safe operation in humid and dusty conditions typical of production lines and field environments.

With compact dimensions (5.5 × 3.1 × 10.9 cm) and 2 × AAA battery operation, the instrument is easily portable. Its drop-sample design minimizes sample preparation time and reduces waste generation.
