    Alcohol/Brix Refractometer for Wine/Beer Brewing

    $80.00
    The digital refractometer is a hand held portable refractometer. Alcohol refractometer is used to measure the alcohol gravity, measurement range has optional 0~60% and 60~80%. Beer refractometer can measure brix scale of 0~40% and wort specific gravity of 1.000~1.130, is an ideal meter for beer raw juice measurement. Wine refractometer has a dual measurement range of alcohol and brix, alcohol range is 0~25%, and sugar measurement range is 0~40%. Fruit wine refractometer can measure 0~14 °Oe (Oechsle) and 0~27 KMW Babo. The refractometer combines the functions of alcohol refractometer and brix refractometer, it is ideal for beer and wine brewing.

    Refractometer is a meter that uses light to measure the concentration of liquid. When the light passes through liquid with different concentrations, there will be different refractive angles, and liquid concentration value can be obtained by comparing refractive angles. Refractometer is designed according to this principle, common products include alcohol refractometer, brix refractometer, beer refractometer, wine refractometer, etc. Digital refractometer is widely used in wine/beer brewing, petrochemical, light industry food, medical and health industries, etc.

    Alcohol/Brix Refractometer Calibration Steps

    1. Open daylight plate, and place 2-3 drops of distilled water on the main prism. Close the daylight plate so the water spreads across the entire surface of the prism without air bubbles or dry spots. Allow the sample to temperature adjust on the prism for approximately 30 seconds before going to step #2. (This allows the sample to adjust to the ambient temperature of the refractometer)
    2. Hold daylight plate in the direction of a light source and look into the eyepiece. You will see a circular field with graduations down the center (you may have to focus the eyepiece to see the graduations clearly). The upper portion of the field should be blue, while the lower portion should be white.
    3. Look into the eyepiece and turn the Calibration Screw until the boundary between the upper blue field and the lower white field meet exactly on the zero scale, such as shown in the image. That is the end of the calibration process. Make sure the ambient room temperature is correct for the solution you are using (20℃/68℉).When working temperature of the room or environment (not the sample) changes by more than5℉, we recommend recalibrating to maintain accuracy. If the instrument is equipped with Automatic Temperature Compensation system, the ambient working temperature of the room must be 20℃ (68℉) whenever the instrument is recalibrated. Once calibrated, shifts in ambient temperature within the acceptable range (10℃~30℃ ) should not effect accuracy.

    Alcohol/Brix Refractometer Use Steps

    1. Place a few drops of the sample to be tested onto the main prism, close the daylight plate and check reading.
    2. Take the reading where the boundary line of blue and white cross the graduated scale.
    3. The scale will provide a direct reading of the concentration.

    Tips: Alcohol/Brix Refractometer Maintenance

    1. Accurate measurement depends on careful calibration. The prism and sample must be at the same temperature for accurate results.
    2. Do not expose the refractometer to damp working conditions, and do not immerse the refractometer in water. If the refractometer becomes foggy, water has entered the body. Call a qualified service technician to solve it.
    3. Do not measure abrasive or corrosive chemicals with refractometer. They can damage the prism coating.
    4. Clean the refractometer between each measurement using a soft, damp cloth. Failure to clean the prism on a regular basis will lead to inaccurate results and damage to the prism coating.
    5. Refractometer is an optical meter, It requires careful handling and storage. Failure to do so can result in damage to the optical components and its basic structure. With care, refractometer will provide years of reliable service.
