Use these Brix refractometers to measure concentration of fruits, beverages, and canned goods; total solid content of syrups, vinegar, and sauces; or check the quality of vegetable, fruit, and grass tissues. Refractometers can also be used for chemical, agricultural, manufacturing process control, quality control, preshipment, and other applications. Brix refractometers feature a screw potentiometer for calibration and easy-to-read numbers on internal scale for excellent resolution. Models with automatic temperature compensation (ATC) are perfect for applications where the temperatures of your samples vary. Refractometers are made of Polybutylene terephthalate (PBT) thermoplastic. Precision accuracy ensures process and quality control across the entire Brix range!
