Atago PAL-41S Calcium Chloride Refractometer

The PAL-41S is a digital handheld refractometer specifically calibrated to measure calcium chloride aqueous solution concentration in g/100g units. Manufactured by Atago, it delivers results in just 3 seconds using only 2–3 sample drops.

With a 0.0–35.0% measurement range and ±0.2% accuracy, it provides reliable results for de-icing solution preparation, industrial process control, and quality assurance applications. Automatic temperature compensation between 10°C–40°C ensures consistent measurements in both field and laboratory environments. IP65 protection rating shields the unit against dust and water exposure, making it particularly practical for field deployment. Battery-powered operation (2×AAA) ensures portability.

Ideal for de-icing agent manufacturers, municipal winter road maintenance crews, and chemical solution production facilities seeking a practical on-site measurement solution.
