Gold / Platinum Tester MZ-K300

The high-capacity, automated electronic balance for direct digital readings of gold Karat number, purity percentage, and density. Relying strictly on traditional touchstone acid tests or surface-level scanners leaves high-volume precious metal buyers exposed to thick gold-plated counterfeits with tungsten or lead cores. The MZ-K300 Precious Metal Densitometer utilizes hydrostatic water displacement principles to measure the entire mass of a piece non-destructively. Featuring an expanded 300g weighing capacity and a standard RS-232 interface for direct printer/PC connectivity, this automated instrument allows gold buying desks, bullion dealers, and pawnbrokers to process larger jewelry items and melt-lots with absolute transparency.

Advantages

• Direct Digital Karat & Purity Output: Eliminates manual lookup charts and multi-step calculations. The specialized internal software automatically cross-references dry mass versus submerged fluid mass, immediately displaying gold Karat values on the digital screen.

• 0.001g/cm³ Density Precision: Despite its heavy-duty capacity, the unit delivers highly repeatable specific gravity results down to a single milligram per cubic centimeter, tracking down micro-porosity in cast batches.

• RS-232 Communication Interface: Arrives equipped with a standard RS-232 data port. This allows the balance to sync with external analytical printers to instantly generate physical purity receipts for customers, building bulletproof retail trust.

• Integrated Environmental Shield Assembly: The structural upper enclosure features a built-in top-loading lid mechanism. This insulates the hydrostatic water tank from ambient room drafts and air currents during the critical submersion reading phase.
