Overview
AR-300K density tester is a practical series of products launched by DAHOMETER brand based on multi-year density measurement technology through simplified function and optimized structure. The instrument has the characteristics of good measurement Repeatability, high accuracy and simple operation. It is mainly used in jewelry industry, jewelry testing center, banking industry, pawn industry, mining, precious metal recovery and material research laboratories. Without destroying the sample, it only takes two steps to accurately and quickly measure and display gold K value, purity percentage and density, platinum PT value, purity percentage and density, silver S value, purity percentage and density, and purity percentage and density value of Miscellaneous alloy.
Features
1. Fast measurement without cutting the sample.
2. Can distinguish the authenticity of gold, K gold, platinum, silver and Miscellaneous precious metals.
3. It can detect whether the content of gold, K gold, platinum, and silver is consistent with the label.
4. The K value and purity percentage of gold, silver, copper, gold and silver can be switched cyclic.
5. Balance function of density measurement and weighing.
6. Miscellaneous liquids or water may be used as the measurement medium.
7. Equipped with a large-capacity PC material sink.
8. With actual water temperature compensation function.
9. Equipped with a special windproof dust cover.
Principle
AR-300K density tester is based on the principle of Archimedes buoyancy method for measurement. By measuring the weight of the sample in the air and the buoyancy in the liquid medium, combined with the medium density and other parameters, the density and precious metal content of the sample are calculated.
Applications
Jewelry industry, jewelry testing center, banking industry, pawn industry, mining, precious metal recycling, precious metal material research laboratory
Steps
1. Place the sample on the measurement table and measure its weight in the air.
2. Immerse the sample in a liquid medium and measure its buoyancy.
3. The instrument automatically calculates and displays the density of the sample and the content of precious metals.
Notice
• Minimum Weight of the instrument is 4g, please ensure that the sample weight meets the requirements.
• Before measurement, the density should be set according to the actual liquid medium (such as water) used.
• Before use, it is recommended to perform one-button correction or use the automatic detection function to ensure accuracy.
• Power supply voltage range is AC100V~ 240V 50HZ/60HZ.
• Please use and maintain the special windproof and dust cover properly.
