Frequently Asked Questions

How do I perform zero calibration on the Soif VAB3T?

Open the cover and clean the prism surface with soft cotton cloth. Apply 1–2 drops of distilled water to the prism, close the cover, and verify that the black separation zone aligns with the zero mark. If needed, adjust using the zero adjustment screw.

What is the proper measurement procedure?

Hold the refractometer from the body toward light with the prism facing forward. Position the diopter adjustment ring to your eye and rotate left/right until the measurement scale appears sharp. Open the cover, apply 1–2 drops of sample liquid to the prism, close the cover, and read the measurement value.

How should I maintain the refractometer?

Never rinse the device with water after use. Optical components must not be wiped with hard objects. Protect from corrosive environments and impact. Clean the prism and cover surfaces after each measurement using soft cotton cloth. Non-compliance with these guidelines voids the warranty.

Why is reference temperature important?

The reference temperature is 20°C. For measurements at different temperatures, correction tables must be applied to ensure accuracy. Since this model has no automatic temperature compensation, manual correction is required.

What accessories are included?

The Soif VAB3T includes a sample tube (absorption tube) and a calibration/adjustment key.

Can this refractometer be used underwater or in wet environments?

The IP65 protection class allows the device to withstand water spray but should not be immersed. The device must never be rinsed with water after use to maintain optical integrity.
