Overview
XFMD-6205K touch screen gold purity tester is a precision measuring instrument using the principle of Archimedes water replacement method. It is suitable for jewelry industry, bank, pawnshop industry and gold and precious metals research laboratory, and conforms to the national GB/T1423 noble metal purity determination method specification.
Features
1. Adopt touch screen operation, the interface is intuitive and convenient.
2. Based on the principle of aquimi's water displacement method, the measurement is accurate.
3. Comply with the national GB/T1423 specification for the determination of purity of precious metals.
4. Wide weighing range and high density accuracy.
Principle
The instrument is based on the principle of aquimide's water displacement method for measurement. By measuring the difference in weight of the sample neutralized in air in water, combined with the density of the water, the density of the sample is calculated, and then its purity is evaluated.
Applications
Jewelry, banking, pawnshops, gold and precious metals research laboratories
Standards
GB/T533、ISO2781、ASTMD297-93、DIN 53479、ASTMD792、D618、D891、ISO1183、GB/T1033、ASTM D792-00、JISK6530、GB/T1423
Steps
1. Turn on the instrument and initialize and calibrate.
2. The sample to be tested is weighed in air and the weight is recorded.
3. Submerge the sample completely in water (using a hanging basket, etc.) and weigh it again.
4. The instrument automatically calculates and displays the density value of the sample according to the two weighing results.
Notice
• Make sure the instrument is calibrated before use.
• Make sure the sample is completely submerged in water and free of bubbles during measurement.
• Please select the model with the appropriate range according to the sample weight.
• The operating environment should be kept stable to avoid vibration and airflow interference.
• Regularly clean and maintain instruments to ensure measurement accuracy.
