Beskrivning på engelska:
Gemological (Gemstone) Refractometer is your primary and most powerful tool in gemstone identification. As with a typical critical angle refractometer, it will measure the Refractive Index of faceted stones
Refractive Index is one of the most important optical parameters used to identify and authenticate polished precious and semi-precious gemstones.
The Gemological refractometer is a low cost, lightweight measuring instrument used by jewellers and traders of gemstones to measure polished stones over a refractive index range of 1.35 to 1.81 RI.
Specifications :
hard CZ measuring prism.
measuring range:1.35-1.81.
Error: ≦±0.002.
Professional optical design.frosted aluminum alloy table.internally installed the quasi monochromatic light.
There are two ways of inputing the voltage:7﹟batteries and DC3V direct current suply(AC100—240V).
2ml refractive index oil (1.78±0.005) with unique design of the bottle(Proprietary technology ZL200620096730.7)
