aichose Brix Refractometer with ATC (0-32%) Instruction Manual

1. Pengenalan

The aichose Brix Refractometer with Automatic Temperature Compensation (ATC) is a precision optical instrument designed for measuring the sugar content (Brix) in various liquid solutions. It is commonly used in applications such as wine making, home brewing, fruit juice production, and other agricultural or industrial processes requiring accurate sugar concentration readings. This device offers a Brix range of 0-32% with a reading resolution of 0.2% and an accuracy of +/-0.2%.

This manual provides detailed instructions for the proper setup, operation, maintenance, and troubleshooting of your refractometer to ensure accurate and reliable measurements.

Familiarize yourself with the main components of your aichose Brix Refractometer:

Rajah 2.1: Labeled components of the aichose Brix Refractometer.

• Daylight Plate: A transparent cover that protects the prism and flattens the sampcecair.
• Main Prism Assembly: The optical component where the sample is placed for measurement.
• Skru Penentukuran: Used to adjust the zero point of the refractometer.
• Pegangan Getah: Memberikan cengkaman yang selamat dan selesa.
• Pelarasan Fokus: Rotates to bring the scale into clear focus.
• kanta mata: The viewing lens through which the Brix scale is observed.

3. Persediaan dan Penentukuran

Before first use and periodically thereafter, the refractometer must be calibrated to ensure accurate readings. Calibration should be performed at room temperature (approximately 20°C / 68°F).

1. Clean the Prism: Open the daylight plate and carefully clean the prism surface with a soft, lint-free cloth.
2. Apply Distilled Water: Place 2-3 drops of distilled water onto the main prism assembly. Close the daylight plate gently, ensuring the water spreads evenly across the prism without air bubbles.
3. Observe the Scale: Point the refractometer towards a light source and look through the eyepiece. Rotate the focus adjustment until the scale is clear.
4. Adjust Zero Point: The boundary between the blue and white fields should align with the '0' mark on the Brix scale. If it does not, use the included screwdriver to turn the calibration screw until the boundary aligns perfectly with '0'.
5. Clean After Calibration: Wipe the distilled water off the prism and daylight plate with a clean, soft cloth.

4. Arahan Operasi

Once calibrated, your refractometer is ready for use.

1. Sediakan Sample: Ensure your liquid sample is at room temperature for optimal accuracy, as the ATC feature compensates for minor temperature variations but extreme differences can affect readings.
2. Clean Prism: Open the daylight plate and clean the prism surface thoroughly with a soft, lint-free cloth.
3. Mohon Sample: Using a dropper, place 2-3 drops of the liquid to be tested onto the main prism assembly. Close the daylight plate gently, allowing the liquid to spread evenly without air bubbles.
4. Baca Pengukuran: Point the refractometer towards a natural light source (avoid direct sunlight) and look through the eyepiece. Rotate the focus adjustment until the scale is clear. The reading is taken at the point where the blue and white boundary intersects the Brix scale.
5. Record Reading: Note the value indicated by the boundary line.
6. Bersihkan Selepas Penggunaan: Immediately after each measurement, clean the prism and daylight plate with a damp, soft cloth and then dry it completely. Residual sugar can crystallize and damage the prism.

5. Aplikasi

The aichose Brix Refractometer is suitable for a wide range of applications requiring sugar content measurement:

• Beverage Industry: Measuring Brix in fruit juices, soft drinks, wine, and beer wort.
• Pengeluaran Makanan: Checking sugar levels in jams, jellies, syrups, and other food products.
• Pertanian: Determining ripeness of fruits and vegetables.
• Home Brewing & Winemaking: Monitoring fermentation progress and final sugar content.

6. Penyelenggaraan dan Penjagaan

Penyelenggaraan yang betul memastikan ketahanan dan ketepatan refraktometer anda.

• Pembersihan: Always clean the prism and daylight plate immediately after each use. Use a soft, damp cloth. For sticky or sugary residues, a small amount of mild soap solution can be used, followed by wiping with a clean, damp cloth and then drying completely.
• Storan: Store the refractometer in its protective case in a dry, cool, and dust-free environment. Avoid exposure to direct sunlight or extreme temperatures.
• Pengendalian: Handle the instrument with care. Avoid dropping it or subjecting it to strong impacts.
• Elakkan Rendaman: Do not immerse the refractometer in water or any other liquid.
• Penjagaan Lensa: Do not touch the optical lens surfaces with bare fingers. If cleaning is necessary, use a lens cleaning cloth.

7. Penyelesaian masalah

If you encounter issues with your refractometer, consider the following:

• Bacaan Tidak Tepat:
  • Penentukuran: Ensure the refractometer is properly calibrated to '0' with distilled water before each use or if readings seem off.
  • Suhu: While the device has ATC, extreme temperature differences between the sample and the refractometer can affect accuracy. Allow the sample to reach room temperature.
  • Pembersihan: Residue on the prism can lead to incorrect readings. Ensure the prism is clean and dry.
  • Sample Permohonan: Pastikan sample spreads evenly across the prism without air bubbles.
• Blurry Scale:
  • Pelarasan Fokus: Rotate the focus adjustment ring on the eyepiece until the scale is sharp and clear.
  • Pencahayaan: Pastikan anda viewing the scale under sufficient, even light.
• Blue/White Boundary Not Visible:
  • S cukupample: Ensure enough liquid (2-3 drops) is applied to cover the prism.
  • Sumber Cahaya: Point the refractometer towards a bright, even light source.
