Overview
XFMD-3201K touch screen gold purity tester is a precision measuring instrument designed based on the principle of Archimedes water replacement method, which is suitable for jewelry industry, bank, pawnshop industry and gold and precious metals research laboratory. The instrument conforms to the national GB/T1423 precious metal purity determination method specification and refers to a number of international standards.
Features
1. Adopt touch screen operation, the interface is intuitive and convenient.
2. Measurement range, weighing range 0.001~ 320g.
3. Measurement accuracy of high density, up to 0.0001g/cm ³.
4. Comply with national and many international standards.
Principle
The instrument adopts the principle of aquimide's water displacement method, calculates the volume of the sample by measuring the weight difference of the sample in air neutralized in water, combines the density of water, and then accurately determines the density of the sample, which is used to analyze the purity of precious metals such as gold.
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. Place the instrument on a stable bench and turn it on.
2. Use the touch screen to calibrate and set parameters.
3. Weigh the sample in air.
4. Immerse the sample in water (using auxiliary devices such as hanging baskets) and weigh its weight in the water.
5. The instrument automatically calculates and displays the density value of the sample according to the two weighing results.
Notice
• Please ensure that the instrument is placed in a stable and vibration-free environment before use.
• Strictly follow the operation steps for measurement to ensure that the sample is completely immersed and free of bubble adhesion.
• Regularly calibrate the instrument to ensure Measurement accuracy.
• Do not use corrosion liquids or samples that exceed the specified range for measurement.
• Keep the measurement table and hanging basket parts clean and drying.
