Product Overview: The PAL-3 Wide Range Refractometer:
The ATAGO PAL-3 is a high-performance digital hand-held "Pocket" refractometer designed with a full measurement range (Brix 0.0 to 93.0%), making it perfectly suited for measuring almost any sample, from low concentration juices to highly concentrated jams or syrups. This instrument has been modified to achieve a high measurement accuracy of $\pm 0.1%$ Brix, establishing it as the highest accuracy model in the standard PAL series.
Advanced Design and Durability:
The PAL-3 is engineered in pursuit of an ergonomic and easy-to-use architecture, resulting in a "palm-fitting" masterpiece ideal for single-handed operation. The unit is designed to be high in hygienic properties, reducing the risk of a germ reproductive environment by minimizing unnecessary assembly parts. The design is completely washable and complies with HACCP, GMP, and GLP system standards.
Key Features include:
• Extreme Water Resistance: The unit is classified under International Protection Class IP65 (Dust-tight and protected against water jets). It can be washed entirely under running water and is designed to float if accidentally dropped in water.
• External Light Interference (ELI) Feature: This revolutionary technology ensures accurate measurements even when used outdoors where intense direct light might otherwise interfere with the sensor, providing consistent results.
• Automatic Temperature Compensation (ATC): The PAL-3 is equipped with ATC to ensure precise measurements across varying temperatures, accommodating measurement temperatures up to $100^{\circ}\text{C}$.
• Ergonomics: The innovative design makes it easy to pour out and remove a sample, while simultaneously making it difficult to accidentally spill the sample.
Operation and Measurement:
The measurement method is quick and simple: simply apply 2 to 3 drops of the sample onto the prism surface, press the START key, and the measurement value and prism temperature are displayed on the Liquid Crystal Display (LCD) in approximately 3 seconds. The SUS (Stainless Steel) sample stage is designed to allow the sample temperature to quickly and evenly conform to the prism temperature for high-accuracy readings.
