Refractometers – Handheld – Analog – MASTER-53α

MASTER-53α Handheld Analog Refractometer is a versatile handheld optical instrument designed for measuring the sugar concentration (Brix) of a wide range of liquid and semi-solid food products. It is commonly used in the food and beverage industry for quality control of items such as fruit juices, coffee, soft drinks, sauces, tomato-based products, and low-calorie jams.
Built for practicality and durability, the MASTER-53α Handheld Analog Refractometer features automatic temperature compensation (ATC), allowing it to deliver stable and accurate readings even when sample temperatures vary. This makes it especially useful in production environments where samples are often tested immediately after processing.
The instrument is also designed with a water-resistant structure rated to IP65, ensuring reliable performance in wet or washdown environments commonly found in food production facilities. This enhances both durability and ease of cleaning, making it suitable for frequent daily use.
The MASTER-53 series is available in two body materials to suit different application needs. The standard MASTER-53α Handheld Analog Refractometer features a metal body for general-purpose use, offering robustness and long-term durability. For more aggressive samples such as salty or acidic substances, the MASTER-53Pα Handheld Analog Refractometer is recommended, as its plastic construction provides improved resistance to corrosion while maintaining identical measurement performance.
Both versions share the same specifications and measurement capabilities, ensuring consistent results regardless of the chosen material. Manufactured by Atago, these refractometers reflect a strong commitment to accuracy, reliability, and user-friendly design.
