AtagManual Arahan Refraktometer Brix MASTER-2M

Produk Selesaiview

Atago MASTER-2M Brix Refractometer is a precision instrument designed for measuring the concentration of various solutions, primarily focusing on Brix values. It is suitable for applications such as measuring the concentration of fruits, beverages, and canned goods, determining the total solid content of syrups, vinegar, and sauces, and assessing the quality of vegetable, fruit, and grass tissues. This refractometer is also utilized in chemical, agricultural, manufacturing process control, quality control, and pre-shipment inspections.

Constructed from Polybutylene terephthalate (PBT) thermoplastic, the MASTER-2M features a screw potentiometer for calibration and an easy-to-read internal scale, ensuring excellent resolution and precision accuracy across its Brix range of 28.0 to 62.0%.

Persediaan

1. Membongkar: Carefully remove the refractometer from its packaging. Inspect for any visible damage.
2. Suai kenal: Identify the main components: the prism, daylight plate, calibration screw, and eyepiece.
3. Pembersihan Awal: Before first use, gently clean the prism and daylight plate with a soft, lint-free cloth.
4. Penentukuran:
   • Ensure the refractometer is at room temperature (20°C / 68°F).
   • Open the daylight plate. Place a few drops of distilled water onto the prism.
   • Close the daylight plate gently, ensuring the water spreads evenly without air bubbles.
   • Look through the eyepiece towards a light source. The boundary line between the blue and white fields should be visible.
   • Use the calibration screw (usually located near the eyepiece or prism) to adjust the boundary line to the '0' mark on the scale.
   • Wipe the prism and daylight plate dry with a soft cloth after calibration.

Arahan Operasi

1. Sample Penyediaan: Pastikan sample is well-mixed and free of solid particles that could scratch the prism. The sample should be at a consistent temperature, ideally room temperature, for accurate readings.
2. Applying the Sample: Open the daylight plate. Place 2-3 drops of the liquid sample onto the surface of the main prism.
3. Closing the Daylight Plate: Gently close the daylight plate so that the liquid spreads evenly across the entire surface of the prism without air bubbles or dry spots.
4. Taking a Reading:
   • Point the prism end of the refractometer towards a bright light source (e.g., daylight or a lamp).
   • Look through the eyepiece. You will see a circular field with a scale.
   • The boundary line between the upper blue field and the lower white field indicates the Brix value on the scale.
   • Read the value where the boundary line intersects the scale.
5. Pembersihan Selepas Penggunaan: Immediately after each measurement, clean the prism and daylight plate thoroughly with a soft, damp cloth or tissue. Dry completely with a clean, lint-free cloth. Residual sugar or other substances can crystallize and damage the prism.

Penyelenggaraan

• Pembersihan: Always clean the prism and daylight plate immediately after each use. Use only soft, lint-free cloths. For stubborn residues, a small amount of distilled water can be used, but avoid harsh chemicals or abrasive materials.
• Storan: Store the refractometer in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it in its protective case when not in use to prevent dust accumulation and physical damage.
• Elakkan Rendaman: Do not immerse the refractometer in water or any other liquid. It is not waterproof.
• Tangani dengan Berhati-hati: The prism is a delicate optical component. Avoid dropping the instrument or subjecting it to strong impacts.
• Penentukuran Biasa: Calibrate the refractometer with distilled water before each use or at least daily to ensure accuracy.

Menyelesaikan masalah

• Reading is Inaccurate:
  • Ensure the refractometer has been properly calibrated to '0' with distilled water.
  • Semak sama ada sample and refractometer are at a stable room temperature. Significant temperature differences can affect readings.
  • Verify the prism and daylight plate are clean and free of residue or scratches.
• Boundary Line is Faint or Unclear:
  • Ensure sufficient light is directed towards the prism.
  • Semak sama ada sample is spread evenly across the prism without air bubbles.
  • Adjust the focus of the eyepiece by rotating it until the scale and boundary line are sharp.
• Air Bubbles in Sample:
  • Gently lift the daylight plate and re-close it, allowing the sample to spread.
  • Ensure only 2-3 drops of sample are used; too much or too little can cause issues.
• Scale Appears Dirty:
  • This usually indicates dirt or residue on the prism or daylight plate. Clean thoroughly as per maintenance instructions.
  • If the internal optics appear dirty, do not attempt to disassemble the unit. Contact customer support.
