FAQ's of Gem Refractometer:

Q: How do I use the Gem Refractometer to measure gemstone refractive indices?

A: To measure a gemstone's refractive index, place a drop of calibration liquid on the prism and position the gemstone face-down. Use the optical eyepiece to view the analog scale. Illuminate with daylight or switch on the built-in LED for clear readings. Adjust the eyepiece focus as needed for clarity.

Q: What types of environments is this refractometer suitable for?

A: The refractometer is designed for versatility and can be used in laboratories, gemological fieldwork, or jewelry stores. Its stable operation within a 0C-40C temperature range and robust construction make it suitable for both professional and field settings.

Q: When should the refractometer be calibrated, and what is the process?

A: Calibrate the refractometer periodically or whenever you notice inconsistent results. Apply the included calibration liquid to the prism, view the scale through the eyepiece, and adjust the calibration control until the correct value displays. Regular calibration ensures ongoing measurement accuracy.

Q: Where can I find the required power source for this refractometer?

A: The refractometer operates with ambient daylight or its built-in yellow LED, which is powered by a standard battery (included when the LED option is present). No external voltage supply is needed, making it portable and convenient for any location.

Q: What accessories are included with the refractometer package?

A: Each package comes with calibration liquid, an eyepiece cloth for cleaning, an instruction manual, and a sturdy storage case, ensuring you have all necessary components for setup, maintenance, and transport.
