PRESIDIUM® Refractive Index Meter II (PRIM II) is a premium portable desktop device that utilizes the properties of reflectivity accurately verify diamonds, diamond simulants and synthetics, and colored gemstones.

A new generation of refractometer:

Crisp LCD display ◆ Three hours continuous use ◆ USB connectivity for data transfer ◆ Built-in R.I. chart reference ◆ Comprehensive bundled software with R.I. and stone descriptors ◆ Low-battery indicator with auto-shutoff ◆ AC and battery power ◆ One-year manufacturer's warranty

Unlike a traditional refractometer, PRIM II is able to measure the range of refractive index values from 1,000 to ~3,000, therefore covering the commonly known gemstones in the market, including diamonds and moissanite. Testing is fast and easy, without the inconvenience and messy usage of RI liquid. The included software enables the user to further eliminate the list of possible colored gemstones by entering known values such as color, hardness and S.G. value and will return further information on gemstone properties.

PRIM II is powered by one (1) 9V battery (sold separately) or USB (cord and adapter sold separately).

PRIM II is for use with faceted gemstones only.
