Refractometer

Analogue refractometer ORA-G For Gemmology/precious stones The practical and robust design means that it can be used simply, efficiently and on a permanent basis, day in day out The manual effort to convert the value is avoided by the use of several selectable scales and thereby eliminates user error These scales have been specially developed, calculated precisely and checked. Another key feature is the very thin, clear lines The optical system and the prism cover are made from special materials, which enable you to measure with low tolerances The model is fitted with an eyepiece which can be adjusted easily and smoothly to different visual capacities Included in the scope of supply: - Storage box - Calibration solution - Pipette - Cleaning cloth Dimensions (W×D×H): 130 mm x 20 mm x 30 mm Divisions: 0,010 nD Measuring capacity: 1.30 nD - 1 81 nD Scales: Refractive index
