MARK II Benchtop Gold Analyzer
A benchtop X-ray fluorescence (XRF) gold tester is a specialized instrument designed for rapid and non-destructive analysis of gold and other precious metals. These testers are commonly used in jewelry manufacturing, pawn shops, precious metal refineries, and other industries where accurate determination of gold content is important.
MARK II THE GOLD JUDGE
Fast | Accurate| Trusted
SAYGOODBYE TO HARSH ACIDS AND EMBRACE MARK II
Mark II Benchtop Gold analyzer offers a rapid and remarkably precise method for assessing karat or gold content, serving quality control, pricing, and practical utilization needs. It empowers users to conduct an immediate, cost-efficient, and entirely nondestructive examination to ascertain gold content and authenticate alloy composition.
Beyond gold, the device delivers exceptional performance for various other valuable metals of significance. The analyzers are equipped with a comprehensive precious metals suite encompassing elements such as Cr, Mn, Fe, Co, Ni, Cu, Zn, Ir, Pt, Au, Rh, Ru, Pb, Bi, Zr, Pd, Ag, Sn, Sb, Cd, In, Ga, Ge, and W. ( Plus Os for SDD detector)
In a matter of seconds, you can accurately measure the precise content of precious metals in jewelry, coins, and other valuable items using the Napco Mark II benchtop gold analyzer.
FEATURES OF MARK II
- Allow user to operate independently or connected to a computer
- Enables coating/plating detection to distinguish counterfeit gold or gold-plated jewelry.
- Extremely fast and easy to use – read results in seconds from the bright color touchscreen display.
- Avoid using any harsh chemicals or acids that can burn fingers, ruin clothing or damage counters. Compared with the nitric acid detection method, it is simpler, faster and more accurate. Compared with the fire assay gold method, it is faster and more comprehensive, and has comparable accuracy.
- Compact design does not take up much space on the table or counter
- Ergonomic design, equipped with LED lighting, easy to operate in jewelry stores, (accessory)
- Rear view lead glass keeps analytical sample in sight
- Precise determination of the presence and amount of other trace alloying elements and harmful heavy metals (Cd,Pb,In…) elements that may affect value and future refining needs.
- Built-in dual CCD cameras can easily realize precise positioning of samples (two functions).
- Optional small spot collimator (3mm, 10mm) can be used to detect smaller samples.
- Optional external portable printer, external balance, display, etc.
- Battery operated, portable
Performance You Can Trust
Napco Mark II benchtop gold analyzer is offered in two versions: the standard Mark II and the high-performance Mark II Plus. The standard Mark II features a Si-PIN detector that delivers exceptional precision and sensitivity for most scenarios. On the other hand, the high-performance Mark II Plus boasts an advanced silicon drift detector, enhancing precision and sensitivity.
The high-performance Mark II Plus model provides a twofold enhancement in precision and sensitivity compared to the standard variant, resulting in superior detection limits. This model is particularly recommended for refiners requiring rapid reading times and the highest level of analytical accuracy. The standard Mark II benchtop gold analyzer, however, is well-suited for general karat assessment and trading purposes.

Advantages of Mark II
Remarkably fast and user-friendly
Just close the lid and press a button. Within seconds, you’ll see results displayed on a vibrant touch-screen color monitor. No need to handle harsh chemicals or acids that could cause burns, damage attire, and harm surfaces.
Reliably accurate and precise
Achieving fire assay comparable outcomes, the analyzer helps prevent losses resulting from the acquisition of under-karated or counterfeit materials.
Designed for practicality
Tailored for retail environments, Napco Mark II precious metal analyzers are factory-calibrated and ready for use upon arrival. The closed-beam design ensures no x-ray exposure to customers or operators.
Detection of gold plating
Efficient to tackle the challenge of identifying gold-plated items, including gold-plated silver, gold-plated copper, steel, tungsten, and other non-gold substrates.
Non-destructive
In contrast to destructive testing methods like acid and fire assay, the tested samples remain intact and unharmed, preserving their original state.
