Description
Introducing a classic gemological refractometer, a tool for every gemologist and jewelry, who needs accurate and reliable measurement of the refractive index of gems between 1.30 and 1.81. Its excellent accuracy and simplicity of use makes this refractometer an indispensable helper to identify and evaluate precious stones.
Main advantages:
- Precise measurement: The measurement range from 1.30 to 1.81 with a minimum division of 0.01 and a high accuracy of ± 0.002, allowing gemologists to determine the true refractive index of each piece.
- Universal use: With the possibility of measuring a double refractive, it is possible to determine whether the gem is single -axis or double -axis and photonegative photonegative.
- Portability: Its small size and low weight 0.4 kg ensure easy portability, ideal for use on the road or directly at the point of view.
Use and range: This refractometer is ideal for jewelers, gem traders and gemological laboratories that need to identify and evaluate gems quickly and efficiently. It is suitable for both field work and laboratory analyzes.
Restrictions of the device: It is important to mention that for correct measurements it is necessary to calibrate and use in a stable environment to avoid errors due to external factors. The measurement range is limited to 1.30 to 1.81 Ri.
