Overview
MDJ-300K gold purity tester is a precision device of XIONGFA brand, which can quickly and accurately measure the fineness (content or purity%) and gold K number of various precious metals, without leaving any traces and contamination to the sample after measurement. It is manufactured with Precision Balance, unique conversion program and specific gravity measurement accessories, and is widely used in gold and silver jewelry stores, banks, pawn shops and other fields.
Features
1. Support one-click automatic clearing and deduction of auxiliary accessories weight operation
2. Fast, accurate and convenient determination of precious metal fineness and gold K number, only 2 steps required, no traces and no pollution
3, with temperature, solution compensation setting function, adapt to different environment needs
4. Unique conversion program directly displays the gold K number and purity%.
5. With mixed specific gravity, gold K number upper and lower limit setting functions, over-limit prompt HI or LO, and with buzzer device
6, can test a variety of precious metal mixing specific gravity, such as platinum, silver, palladium, copper, rhodium, etc
7, the use of integrated transparent measurement sink, anti-wear, corrosion resistance, not easy to break, beautiful
8. With RS-232C interface, it can be connected to computers and printers
9. When gemstone or hollow sample cannot be tested, it can be used for Precision Balance
Principle
Based on the principle of water-specific gravity method, the MDJ-300K gold purity tester measures the weight difference between the sample in air and water through Precision Balance measurement, and calculates the density with a unique conversion program to determine the fineness of the precious metal and the gold K number.
Applications
Gold and silver jewelry stores, banks, pawn shops, jewelry processing plants, precious metals smelters, mass inspection departments, analysis and testing centers, gold and precious metals research laboratories
Steps
1. One-click automatic clearing and deduction of auxiliary accessories weight
2, the measurement operation, only 2 steps to complete the whole process
Notice
• Do not test gemstone-set or hollow samples
• When a specific sample cannot be tested, the instrument can be used as a Precision Balance
