Frequently Asked Questions (FAQs)
· Q: Can this be used for homebrewing beer and making wine?
· A: Absolutely! It is perfect for measuring the sugar content in wort or must. This helps you track fermentation and estimate potential alcohol levels with high precision.
· Q: How do I calibrate the GOYOJO Digital Refractometer?
· A: Calibration is simple. Place a few drops of distilled water on the sensor and press the "CAL" button. This ensures your meter is zeroed out for the most accurate readings possible.
· Q: Is the device waterproof?
· A: While the sampling area is designed to hold liquids, the entire body should not be submerged. We recommend wiping the prism clean with a damp cloth after each use.
· Q: Does it work for high-sugar items like honey?
· A: This model measures up to 55% Brix. While it is perfect for fruits, juices, and beverages, honey typically requires a range of 60-90% Brix. We recommend our high-range model for honey specifically.
· Q: What does ATC mean for my measurements?
· A: ATC stands for Automatic Temperature Compensation. Sugar readings can change based on the temperature of the liquid. The GT128 automatically adjusts the reading so you get the "true" Brix level regardless of whether the sample is warm or cold.
