Handheld refractometer designed to measure the Brix and specific gravity of wort solutions. The Brix scale range is 0–32% with a resolution of 0.2%, and the specific gravity scale range is 1.000–1.130 with a resolution of 0.001. Simple to use: place 2–3 drops of sample onto the main prism, close the daylight plate, and view through the eyepiece to obtain the Brix reading. The device features automatic temperature compensation (ATC) within the range of 10–30°C, ensuring reliable measurements under varying conditions. Equipped with a calibration screw for zero-point adjustment using distilled water, which ensures measurement accuracy. The focusable eyepiece allows for clear visibility of the scale. Suitable for use in the brewing industry to monitor fermentation processes, commonly used by home brewers. Compact, lightweight, and portable design with a durable build. Includes a protective plastic case for safe storage and easy transport. The specific gravity scale provides a quick reading of original gravity. Once fermentation begins and alcohol is present, continued monitoring using the Brix scale is recommended, with appropriate correction calculations applied for final gravity. Requires only a few drops of liquid for accurate results, minimizing sample waste compared to traditional hydrometers. Features: - Product weight: 9g - Length: 170mm - ATC (Automatic Temperature Compensation) range: 10–30°C Instructions: 1. Open the daylight plate and apply 2–3 drops of sample onto the main prism. 2. Close the daylight plate gently to spread the sample evenly. 3. Look through the eyepiece and observe where the light/dark boundary intersects the scale. 4. Adjust the focus by rotating the eyepiece until the reticle scale is clear. 5. Read the value at the intersection line. Scale details: - Brix scale: 0–32% Bx, resolution 0.2% - Specific gravity scale: 1.000–1.130, resolution 0.001 Calibration: Calibrate to "0" using distilled water, which has a Brix value of 0%. This ensures accurate readings. Handling note: The protective plastic case may be tight to open. Use a tool to press the release gently and avoid damaging the contents. Important usage guidelines: - Do not immerse the refractometer in water. - Avoid using solvents to clean the plastic lens. - For honey samples, ensure crystallized honey is fully melted before testing. - Allow hot samples to cool below 40°C before measurement to prevent damage and ensure accuracy. - This refractometer includes both Brix and specific gravity scales. While original gravity can be read directly, final gravity measurements after fermentation require correction due to alcohol interference.
