Overview
AR-900K density tester is a practical series of products launched by DAHOMETER brand based on multi-year density measurement technology. It has the characteristics of good measurement Repeatability, high accuracy and simple operation. The instrument does not need to destroy the sample, and can quickly and accurately measure the K value, purity percentage and density value of precious metals such as gold, platinum and silver in only two steps. It is suitable for jewelry, testing, finance, mining and laboratories.
Features
1. Fast measurement without cutting the sample.
2. Can distinguish the authenticity of gold, K gold, platinum, silver, and other precious metals.
3. It can detect whether the content of gold, K gold, platinum, and silver is consistent with the marked content.
4. You can cycle and switch the K value and purity percentage of gold, silver, copper, gold and silver.
5. Balance density measurement and weighing function.
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-900K density tester is based on the principle of Archimedes buoyancy method for measurement. By measuring the weight difference between the sample in the air and the weight difference 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 a measurement table and weigh it in air.
2. Immerse the sample in a liquid medium in a water tank and weigh it.
3. The instrument automatically calculates and displays the results.
Notice
* Minimum Weight of instrument is 5g.
* Before measurement, set parameters such as water temperature and medium density according to the actual situation.
May use water or Miscellaneous liquids as a medium.
* The instrument has a single-button correction and automatic detection function, and it is recommended to calibrate regularly.
* Use a windproof dust cover configured to reduce environment disturbances.
* Power supply voltage range is AC100V~ 240V 50HZ/60HZ.
