【Precious Metal Detector】: The precious metal density meter is designed to accurately determine the purity of gold and other precious metals.The tester is equipped with a digital display that can display the measured density, weight, density, purity, K number of the tested material, providing accurate values at a glance. Press Mode to display the karatnumber, density, and volume. Press Print to print the test results.(The printer is an optional accessory) 【Non-Destructive Testing】: The Digital Electronic Gold Purity Tester Machine offers non-destructive testing, which means it does not damage or alter the tested material during the analysis process. This non-destructive feature is particularly important for precious metals, as it allows the user to assess the purity without devaluing or damaging the item.
