DH-300K Gold Measuring Machine, Jewelry Weighing Scale, Gold Tester Purity Detector

1. Directly read the purity of gold and measure the density (specific gravity) of other metals. After testing, your gold will not leave any stains and scratches;
2. It takes only 10 seconds to accurately measure the K number and density of gold, the Pt value and density of platinum;

3.Easy to operate, determine the precious metal density (specific gravity) and gold k number / platinum PT value, only need to weigh 2 times, just put the sample into the water, the instrument's internal software will automatically calculate;
4. According to market demand, through special software design, the user can set the upper and lower limits of K number and Pt value. When the test gold K number is greater than 24K, the instrument will display HI; when it is less than 12K, LO will be displayed. Identify the authenticity of gold in a more intuitive and faster way;
5. According to the ratio of copper and silver in gold, set the ratio of copper and silver to compensate the parameter value;
6. It adopts one-piece transparent large water tank (size: 15cm×10cm×9cm). The water tank is formed by special material, which is not only anti-wear and corrosion-resistant, but also not easy to break. It is also very beautiful and can be very convenient for users. use;
7. Lightweight, thin strip and stainless steel hanging bar line design can greatly reduce the error caused by the buoyancy of the hanging bar line;
8. Can test other precious metals, such as silver, copper, tin, etc.; can also be used as a precision electronic balance.
9. Only for solid metal parts, and solid metal parts are not equipped with gemstones;
10.Including RS-232C communication interface, easy to connect PC and printer, optional MZ-P1 printer to print measurement data.
