ERICAT Digital Brix Refractometer User Manual

1. Product Overview

The ERICAT Digital Brix Refractometer is designed to measure the sugar content of various substances, including fruits, food products, beverages, crops, and water samples. It is widely utilized in the food industry, beverage industry, agriculture, and agricultural food processing sectors. This device features automatic temperature compensation for enhanced accuracy and a clear display for easy readings.

Key Features:

• Automatic Temperature Compensation: Built-in temperature detection (5°C-45°C) automatically corrects measurement errors caused by temperature fluctuations, improving sugar detection accuracy.
• High Accuracy: Utilizes a high-precision sensor with a Brix test range of 0-95%. Water temperature does not affect readings.
• Multifunctional Design: Measures sugar content in fruits, juices, and liquids, and can also be used for salinity and brewing applications.
• Accurate Readings: The upgraded screen displays Brix, temperature, refractive index, and other information clearly, even in sunlight.
• Wide Application: IP67 waterproof and drop-resistant, suitable for use by producers, employees, or analysts.

Calibration:

It is crucial to calibrate the device before each measurement session to ensure accurate results. Use pure water for calibration.

4. Operating Instructions

Follow these steps for accurate measurement:

1. Step 1: Prepare for Calibration. Turn on the device. Using the dropper, drip pure water into the prism dish until it covers the prism surface.
2. Step 2: Enter Calibration Mode. Short press the measurement button, then immediately long press it to enter calibration mode. The display will indicate calibration is in progress.
3. Step 3: Apply Sample. After successful calibration (or if not calibrating, after cleaning the prism), drip the liquid sample to be measured into the prism dish. Ensure the sample covers at least 2/3 of the sample tank and fully covers the prism. Do not scratch the prism surface.
4. Step 4: Measure. Short press the measurement button. The result will be displayed on the screen.

5. Care and Maintenance

Cleaning the Prism:

After each use, clean the prism surface thoroughly with the provided wipe cloth or a soft, lint-free cloth. Use pure water to rinse off any residue. Ensure no scratches occur on the prism surface, as this can affect measurement accuracy.

Waterproof and Durability:

The refractometer has an IP67 waterproof rating, meaning it is protected from dust and can withstand immersion in water up to 1 meter for 30 minutes. It is also designed to be drop-resistant, passing a 1.5-meter dropping test.

Storage:

Store the device in the provided storage bag in a cool, dry place when not in use. Avoid extreme temperatures and direct sunlight.

6. Troubleshooting

If you encounter issues with your refractometer, please refer to the following common problems and solutions:

• Inaccurate Readings:
  • Ensure the device is calibrated with pure water before use.
  • Clean the prism thoroughly to remove any residue.
  • Verify that the sample covers the prism sufficiently (at least 2/3 of the sample tank).
  • Ensure the operating temperature is within the specified range (5-45°C).
• Device Not Turning On:
  • Check the battery level and recharge the device if necessary.
  • Ensure the power cable is properly connected during charging.
• Display Issues (e.g., blank screen, flickering):
  • Attempt to restart the device.
  • If the issue persists, contact customer support.
