Contact SupplierMilk Refractometer – Description
A milk refractometer is a precision optical instrument used to quickly and accurately measure the total solids or milk concentration by evaluating its refractive index. This handheld or digital tool is commonly used in dairy farms, milk processing units, and quality control labs to monitor milk quality, detect adulteration, and maintain consistency in production.
Key Features:
Measurement Range:
Typically measures in the range of 0–20% Brix or Total Solids (TS), depending on the model.
Accuracy:
High-precision readings with an accuracy of ±0.2% (varies by model), ensuring reliable quality control.
Calibration:
Simple calibration using distilled water; some models offer automatic temperature compensation (ATC) for consistent readings across varying temperatures.
Construction:
Made from durable, food-grade materials like stainless steel and ABS plastic; often equipped with a rubber grip for safe handling.
Display Type:
Analog refractometers feature a clear scale view through an eyepiece.
Digital models offer an LCD screen for easy readout and additional functions like temperature display.
Portability:
Compact, lightweight, and easy to carry for on-site milk testing.
Application:
Detects dilution or adulteration in milk
Measures milk quality for cheese/yogurt production
Ensures uniformity in dairy processing operations
Benefits:
Fast and non-destructive testing
Requires only a few drops of milk
No electricity (for analog types), ideal for field use
The milk refractometer is a vital tool in the dairy industry for maintaining quality assurance, enhancing product consistency, and ensuring consumer safety.
