Technology Performance
Enables fast, non-destructive, and accurate on-site analysis, displaying element content directly in ppm or percentage.
Compact size, rapid operation, and high precision.
Can analyze both solid and liquid samples such as ores, rocks, slags, fragments, soil, slurry, etc.
Supports intelligent testing for uneven or small samples; even very small samples can be detected and identified.
Simply place the device on the object’s surface to determine ore grade, element types, and content on-site.
Maintains high performance even under direct sunlight and high temperatures, thanks to low power consumption and efficient heat dissipation design.
Built to endure harsh working conditions: Sealed with a wear- and scratch-resistant full metal shell, allowing it to function normally in rainy and dusty mining environments.
Prioritizes user safety for long-term use: Key components are fully sealed in metal to meet the world’s lowest radiation standards.
Equipped with electromagnetic shielding, allowing it to function properly near mobile phones and multiple wireless communication devices.
Features the world’s fastest analysis speed—mineral elements can be identified in just 2 seconds.
Durability and Warranty
Given the environments in which XRF analyzers are often used, durability is crucial. Opt for models that feature:
Rugged Design
Shock-resistant casings and water-resistant components.
Warranty and Support
A solid warranty can provide peace of mind and protect your investment.
A handheld analyzer should have a long battery life, especially if you’ll be using it in remote locations. Look for models with:
Extended Battery Life: A minimum of 8 hours is recommended for uninterrupted use.
Fast Charging: Quick recharge times can minimize downtime.
