The Presidium Refractive Index Meter II detects the
quantity of light (intensity) reflected from the surface of
cut and polished gemstone. This intensity reading is fed
into a microcontroller in which a calculation is performed
and converted to obtain the refractive index reading of the
gemstone
This tester was designed with the following
objectives:
• Reconfirming the identity of colored gemstone using
Refractive Index
• Universal SI units
• Provide fairly consistent and reliable test results under
proper use;
The Presidium Refractive Index (R.I.) Meter II features
the following:
• Separates diamond, moissanite and gemstones in
seconds
• Refractive Index reading from 1.000 to ~ 3.000
• No waiting time between tests
• USB power inlet with International Voltage
Compatibility
• Low battery Indicator
