- * Premium Construction Materials：Crafted with hard aluminum alloy for scratch-proof work platforms, this instrument delivers robust structural integrity. Enhanced with ABS engineering plastic power controls and triple-layer internal insulation, it ensures secure protection against electrical hazards
- * Simplified Testing Procedure：Requires no refractive oil—simply position the gem’s measurement facet against the platform. Instantly determines crystal structure (uniaxial/biaxial) based on light behavior
- * Essential Gem Identification Instrument：As a cornerstone tool for jewelers, it performs non-destructive refractive index measurements (range: 1.300-3.000) with speed and precision. Critical for verifying gemstone authenticity through optical properties
- * Total Internal Reflection Technology：Utilizes fundamental optical principles where refractive index values serve as definitive indicators for material identification. Each reading provides reliable gem characteristic data
- * Comprehensive Material Compatibility：Accelerates identification for single/double refractive gems, diamonds, and colored stones. Engineered for solid materials requiring refractive index verification
