Precious Metal Purity Testes

L300Q-Pluse

The Standard of Trust for Banks & Pawn Broking Institutions

In gold-backed lending and collateral-based finance, accuracy is risk control. The Leotech™ Precious Metal Purity Tester Series is purpose-built for banks, pawn broking institutions, and financial service providers that require fast, transparent, and defensible precious metal purity verification. Using a non-destructive, density-based testing method powered by high-precision German manufactured sensor technology, "L300Q-Pluse" enables officers to verify gold and platinum purity within seconds—without damaging customer assets and without reliance on subjective judgment. The result is faster transactions, reduced disputes, and enhanced institutional credibility. Trusted by financial institutions worldwide, "L300Q-Pluse" supports confident lending decisions at every counter.

Built for Financial Operations

"L300Q-Pluse" is engineered to perform reliably in high-volume, customer-facing environments:

Gold Loan & Pawn Broking Counters
Commercial & State Banks
Microfinance & Leasing Institutions
Cooperative Societies & Rural Banks
Centralized Gold Evaluation Units

Its simplicity, speed, and repeatability make it ideal for both frontline officers and centralized risk teams.

Scientifically Proven Testing Method

"L300Q-Pluse" operates on the Archimedes water buoyancy principle, enhanced by German-engineered microelectronic sensors and compliant with GB/T1423 Precious Metal Testing Standards. By comparing weight in air and liquid, the system automatically calculates:

Gold Karat (K Value)
Purity Percentage (%)
Density (g/cm³)
Platinum Purity (PT Value)
Silver Purity (Si Value)

This method is widely accepted for institutional use as it provides objective, tamper-resistant results while preserving the asset’s condition.
