MDJ-300K Gold Purity Testing Machine/Gold Tester Machine / Electronic Gold Tester NEW USA

Description

• • Non-destructive testing: The machine measures the object’s density to determine its composition without damaging it.

• Density testing method: It operates on the principle of density measurement, which is calculated from the object’s weight in air and its weight when submerged in water.

• Digital display: The machine’s screen shows the calculated results for density, weight, and purity (including Karat).

• Wide applicability: It can test the purity of various precious metals including gold, silver, platinum, and K gold.

• Limitations: It cannot test hollow items or samples with precious stones, and it can be used as a general balance for weighing purposes. 

• Rapid and accurate: It can quickly and accurately display the Karat and density of gold with just two weighing steps.
• Simple operation: The process involves two simple weighing steps.
• Water medium: It uses pure or distilled water, which is inexpensive and easy to obtain, as the medium for testing.
• Built-in rechargeable battery: The machine includes a rechargeable battery for portability and uninterrupted use.
• HI and LO limit function: The machine has a function to set high and low limits for the Karat range from 9K to 24K, according to the user’s requirements.
• Large tank design: The design of a large water tank helps decrease inaccuracy caused by the supporting wire’s buoyancy.
