Gold Testing Machine

Measuring instrument is the most significant features: fast, lossless, accurate. There are many factors that affect the test results of the gold measuring machine. Due to the special circumstances of the jewelry products, the method should be used by the method to detect and be familiar with the following factors (these factors in different circumstances will have a great impact on the collection of characteristic line intensity 2) the surface of the sample to be tested or chemically treated; 3) the time of measurement; 4) the size of the sample to be tested and the content of the material contained in the sample; Shape; 5) the size of the sample measurement; 6) how much the content of precious metals; spectrum of gold machine types in accordance with the appearance to distinguish, there are three, respectively, as follows: 1) desktop: desktop gold machine general volume, weight, External desktop computers, equipment, good stability, high re-dominant. 2) portable: small size, light we

The value of gold depends on its fineness or carat rating. One of the most common and most effective test methods, if a project is a gold, is it through the use of electronic gold tester. Electronic gold test is just an indicator, a project may or may not be gold, its fineness level may be what. However, when using gold medal testers, you should know how to interpret the electronic test results. The electronic gold tester is getting better, but its operation remains the same. Karat is a term used to measure gold content or purity. Calat is basically a unit of measure of gold purity. The higher the carat, the more pure gold. Look at the previous gold inspection techniques and are still used in their markets including: visual inspection, bite test, magnet test, density test, ceramic plate test, and finally nitric acid test. These have been incorporated into our newly designed gold tester system. It makes work easier and more accurate. The electronic gold test is based on its conduct

Every kind of gold has a different kind, and you need to know how to distinguish their true and false . Gold items should be tested before they are sold. You can not venture to sell fake gold items, and there are customers or two people complain about fake jewelry. Anyone can happen. You can provide a fake gold without knowing it, but you can make sure that you get these items from the gold jeweler is real and avoid this dilemma. Whether you are a seller or a terminal consumer, you should know how to distinguish between true and false gold. Skilled people can easily find a fake gold jewelry. According to these professionals, generally from the surface can be seen too shiny or too dark things may not be real gold. But gold can have different colors, from the brilliant yellow into pale yellow. Keep in mind that gold is usually alloyed with other metals to make it more durable. Gold itself is a very weak metal, it is easy to be scratched, but the amount of metal added, the lower the co

Our daily life in the common inspection method is not Kaopu, then the gold test method is what ? 1, the density measurement method is simple and feasible It is understood that the density of gold at room temperature is 19.26 g / cm3 to 19.37 g / cm3, can be more accurate cups into a certain amount of water, and then into the gold bars into the water, measuring the new water, the sum of the two known gold bars The size, and then came to the density of gold bars. If the density is between the standard values, the gold bars are more likely to have a higher color, otherwise they may be doped. Common detection can be used density measurement method, this method is relatively simple, you can exclude some of the doped gold. This method can exclude most of the doped gold, but if the doping of gold through a strict proportion of the addition of other metals, it can not determine the iridium and tungsten, the proportion and the weight of gold and light similar to the measured density is not

Due to the special circumstances of the gold product jewelry products , the use of this method should be aware of and familiar with the following factors (the impact of these factors in different circumstances will have a great impact on the collection characteristics of line strength, and even cause justice) : A) the measured sample and the standard material and content contained in the element content is completely different; B) the surface of the test sample is coated or chemically treated; C) measurement time; D) the shape of the sample; E) the area measured by the sample; F) how much precious metal content; Gold testers test results usually require a comprehensive understanding of the different aspects of jewelry products, using different instruments, testers at different levels of quality, and testing the range of the proposed range. As the precious metal content decreases, the acceptable range will increase. The error range of the measurement result is 0.1% -3%.

Recently, some gold investors have their own gold products have doubts, in the end these gold products and significant purity is the same? Is product quality reliable? To this end, our staff tell you how to detect the purity of gold? How to detect the purity of gold: In the gold detection method, according to whether the destruction of gold products can be divided into non-destructive testing and damage detection methods. The former will not damage the appearance of gold products, will change the appearance of the product can not be restored. One of the most common non-destructive testing methods is the use of water suspension method, that is, the application of Archimedes method to test the density of gold products, and compared with the standard value. The water suspension method has the advantage of being simple to detect and does not damage the metal product to it is also very safe. However, the water suspension in the use of a great deal of limitations have a drawback. The
