Overview
Gold purity tester is a fast and effective gold purity analysis instrument. It does not damage the measurement sample and can quickly display the purity, K value and density value. It has the characteristics of accurate measurement, simple operation, fast, reliable performance and economy.
Features
1. Large-screen LCD display.
It has an RS-232C computer interface and can be connected to a printer.
3. Built-in battery, with Draft Shield, more suitable for field testing.
4. It can quickly and accurately determine the purity of precious metals and the gold K number, requiring only two weighing steps.
5. No traces and contamination will be left after measurement, no need to use sulfuric acid solution or test standard sample.
6. With upper and lower limit functions, a wide range of K numbers from 1K to 24K can be freely set for HI and LO data.
7. With mixing ratio function, it can test other precious metals, such as platinum, silver, palladium, copper, rhodium, etc.
8. Brazilian fire gold with a coating thickness greater than 30 μm can also be easily determined.
9. Special software design, can cycle display gold K number (containing gold copper silver, gold silver, gold copper), gold purity% (containing gold copper silver, gold silver, gold copper).
Principle
The instrument calculates the density of the sample by measuring the weight of the sample in air neutralizing water, combined with built-in algorithms to quickly analyze and display the purity percentage and K value of gold.
Applications
Jewelry, banking, pawnshops, gold and precious metals research laboratories
Standards
Specification for determination method of purity of precious metals
Steps
1. Place the sample in air and weigh it.
2. Immerse the sample in water and weigh it.
3. The instrument automatically calculates and displays purity, K value and density.
Notice
• Ensure that the surface of the sample is clean and drying without attachments.
• Draft Shield is required for measurement to reduce airflow interference.
• When weighed in water, make sure the sample is completely submerged and free of bubbles.
• The instrument has a built-in battery, please pay attention to charging in time to ensure on-site use.
• Do not use sulfuric acid solutions or standard samples for measurement.
• For coating samples, ensure that the coating thickness is greater than 30μm to accurately determine.
