Frequently Asked Questions - DRG 10 PCE Instruments
How do I calibrate the DRG 10 refractometer?
To calibrate, place a few drops of distilled water on the prism, press the CAL button, and wait for the display to show 0.0% Brix. Use a soft cloth to dry the prism before measurements.
What is automatic temperature compensation (ATC)?
ATC adjusts the reading to a reference temperature of 20°C (68°F), ensuring accurate results even if the sample temperature varies between 10°C and 30°C.
What is the measurement range of the DRG 10?
It measures Brix (sugar content) in the range of 0 to 50% with a resolution of 0.1%, which is suitable for most fruit juices, soft drinks, and wine.
Can I measure the refractive index directly?
Yes, the device also displays refractive index from 1.3330 to 1.4200 nD, complementing Brix measurements for quality control.
How should I clean the device after use?
Immediately after each measurement, rinse the prism with clean water and wipe it with a soft, dry cloth. Avoid using abrasive materials to prevent scratching the prism.
What type of batteries does the DRG 10 use?
It uses two 1.5V AAA batteries. Replace them when the low battery indicator appears; typical battery life is around 8,000 measurements.
Is the device waterproof?
The housing is rated IP65, which means it is splash-proof for everyday lab or field use, but it is not designed for submersion.
How do I replace the prism if it gets damaged?
The prism and sealing ring are available as spare parts. Loosen the retaining ring, remove the old prism, place the new one with the sealing ring, and tighten carefully.
Why do my readings drift or show high values?
This often occurs when the prism is dirty or when calibration is performed with non-distilled water. Clean the prism and calibrate with fresh distilled water at room temperature.
Can I measure hot liquids above 30°C?
The ATC range is 10–30°C. For samples outside this range, allow them to cool to within the ATC range before measurement for accurate results.
