SmartPro QUIZ-S High-Precision XRF Precious Metal Analyzer
 
The SmartPro QUIZ-S is an advanced XRF (X-Ray Fluorescence) solution designed for the immediate and reliable analysis of gold, silver, platinum, and precious metal alloys. Engineered for jewelry professionals and metal traders, it delivers laboratory-grade accuracy, high speed, and exceptional ease of use.
 
Utilizing sophisticated QUIZ XRF algorithms, the analyzer provides a comprehensive chemical composition breakdown in just 10 to 60 seconds, allowing for instant verification of alloy purity. Its integrated plating detection feature identifies gold-plated or vermeil items, ensuring maximum security during transactions.
 
The SmartPro QUIZ-S features a precision 1 mm analysis spot and a built-in HD camera, enabling users to target minute points on jewelry with absolute accuracy. This ensures stable and repeatable measurements for every scan.
 
Equipped with a modern 5-inch touchscreen and a transparent protective lid, the device allows customers to observe the testing process in real-time. Additionally, the certified low-radiation system guarantees safe operation, making it perfect for retail showrooms, refineries, pawnshops, and certification labs.
 
Available with either a high-resolution SDD or SiPIN detector, the SmartPro QUIZ-S combines high-performance tech with a sleek, compact design.
