Digital Sugar Refractometer User Manual

1. Product Description

The Handheld Digital Brix Meter is a portable optical measuring instrument designed to determine the sugar concentration of liquids such as fruit juice, beverages, and other food products. The device measures Brix value, temperature, and refractive index using an integrated optical prism and digital sensor system. Automatic Temperature Compensation ensures reliable readings under varying environmental conditions. The compact battery-powered design makes the instrument suitable for field testing, laboratories, agriculture, food processing, and quality control applications.

5. Setup

5.1 Battery Installation

1. Open the battery compartment cover.
2. Insert two AA batteries, ensuring correct polarity (+/-) as marked inside the compartment.
3. Close the battery compartment cover securely.

5.2 Initial Preparation

• Ensure the prism surface is clean before measurement. If necessary, gently wipe the prism using a soft lint-free cloth.

6. Operation

6.1 Measurement Steps

1. Power On: Press the power button (usually marked with a power symbol) to start the device.
2. Apply Sample: Place a small sample of the liquid to be tested onto the optical prism in the measurement groove. Ensure the liquid fully covers at least two-thirds of the prism surface.
3. Measure: Press the measurement button (usually marked 'MEAS') to initiate the test.
4. Read Data: The instrument will automatically analyze the sample and display the Brix value, temperature, and refractive index (if applicable to your model) on the backlit display.
5. Clean: After measurement, clean the prism with distilled water and wipe it dry using a soft cloth before proceeding to the next measurement.

7. Precautions

• This instrument is a precision optical device. Avoid drops or strong impacts.
• Do not scratch the optical prism in the groove with hard or sharp objects.
• Ensure the prism is clean before each measurement to prevent inaccurate readings.
• Do not immerse the instrument in water or other liquids. The instrument is NOT waterproof.
• Store the instrument in a dry environment when not in use.
• Remove the batteries if the device will not be used for a long period to prevent leakage damage.
• Operate the device within normal environmental temperature and humidity conditions.
• USB charging voltage must not exceed DC 6V (if applicable to your model).

8. Maintenance and Storage

• Clean the prism after each measurement using distilled water and a soft cloth.
• Avoid using abrasive materials or chemical solvents on the optical surface.
• Store the instrument in a dry and dust-free location.
• For long-term storage, remove the batteries to prevent leakage damage.
• Regularly check the prism surface and battery contacts to maintain measurement reliability.

9. Troubleshooting

• Inaccurate Readings: Ensure the optical prism is perfectly clean, the sample fully covers the prism surface, and the device has been zeroed correctly. Verify that the sample temperature is within the operating range for accurate Automatic Temperature Compensation (ATC).
• Device Not Turning On: Check if the AA batteries are installed correctly with the right polarity. Replace batteries if they are depleted.
• Display Issues: If the display is dim or unreadable, check battery level and replace if necessary. Ensure the device is not exposed to extreme temperatures.

10. User Tips

• For quick and accurate sugar content checks, always ensure the prism is clean and the liquid sample completely covers the sample well.
• When measuring pulpy juices (e.g., citrus), filter out any solid particles or pulp before applying the sample to the prism for the best accuracy.
