Overview
ATAGO refractometers are precision instruments designed and manufactured in Japan, offering high functionality in a compact size. They are used for measuring the concentration of solutions using light refraction.

Specifications

• Digital Salt Meter ES-421: Measures salt concentration from 0.00 to 10.0% with a minimum indication of 0.01% for lower concentrations and 0.1% for higher concentrations. It has a measurement accuracy of ±0.05% for concentrations up to 1.00% and relative precision of less than 5% for higher concentrations. Powered by a 9V battery, it weighs 300g.
• Digital Refractometer PR-R: Measures refractive index from 1.3306 to 1.4436 and temperature from 5 to 45°C. It has a measurement accuracy of ±0.0002 for refractive index and ±1°C for temperature. Also powered by a 9V battery, it weighs 300g.

Palette Series Features
The Palette series offers improved accuracy of ±0.1% Brix, automatic temperature compensation, and a user scale feature for various liquid concentrations. It includes models PR-32, PR-101, PR-201, and PR-301, each with specific measurement ranges and applications.

Key Features

• External Light Interference (ELI) technology to ensure accurate measurements even in intense lighting conditions.
• Large, easy-to-read display and convenient temperature display function.
• Two-year warranty for the Palette series.

Applications
The refractometers are suitable for use in fruit and vegetable farming, beverage factories, food factories, markets, restaurants, and educational institutions.

Certification
ATAGO provides calibration and certification in accordance with ISO Quality Management Systems, offering documents such as Calibration Certificate, Traceability System Diagram, and Traceability Certificate for a service fee.
