Frequently Asked Questions

How do I perform zero calibration on the refractometer?

Open the prism cover and apply 1-2 drops of distilled water. Close the cover gently and observe the boundary line (shadow line) in the measurement scale. It should align precisely with the zero reference line. If misaligned, use the calibration screw to adjust until the boundary line matches the zero mark exactly.

What is the importance of temperature matching during calibration?

The calibration liquid and measurement sample must be at the same temperature. If there is a significant temperature difference (>5°C), allow the instrument and sample to equilibrate for 30 minutes before performing zero adjustment to ensure accuracy.

How should I clean the refractometer after use?

Never rinse the instrument with water after use. Clean the prism and cover surfaces with a soft cloth using only distilled water. Optical components must not be wiped with hard or abrasive materials.

What maintenance precautions should I take?

Protect the instrument from corrosive environments and mechanical shocks. Store in a clean, dry location. Do not expose optical components to hard contact. Improper handling may void the warranty.

What is the difference between VWN1, VWN2, and VWN3 models?

VWN1 measures °Oe, KMV Babo, and mash sugar with 0.5% Brix resolution. VWN2 measures only °Oe with 0.1 °Oe resolution (higher precision). VWN3 measures °Oe and Brix with 1% Brix resolution. Choose based on your required measurement units and precision needs.
