The MR62ATC is a handheld optical refractometer purpose-built for applications where sugar concentration starts above the typical fresh fruit or grape range. Its 28–62% Brix window makes it ideal for checking set points in jam and marmalade production, assessing honey maturity, monitoring concentrated sugar syrups, and confectionery quality control — situations where a 0–50% instrument simply runs out of scale. With 0.2% resolution and ±0.2% accuracy, it delivers reliable results without batteries or electronics: place a few drops on the prism, close the daylight plate, and read through the eyepiece.
Automatic temperature compensation (ATC) removes the need for manual correction tables, maintaining consistent readings across typical ambient conditions.
