Why choose the gold test machine

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 conductive test gold project. This is done by using gold testers. This gold test provides this critical message: it is very close to the fineness of the gold project (10K, 14K, etc.), indicating whether the item is a karat gold alloy (6K and above), indicating whether the item is not gold

The gold tester provides high reliability, non-destructive, approximate fineness, no danger, and test quality rather than just surface, safety (follow the instructions), speed (most results ready in 2-15 seconds), portable (You can use it anytime, anywhere, most testers use the battery), easy to use (compared to other test methods, you still need to read and follow the instructions), simple results show - LED lights show karat range or digital readings more Expensive models with a carat value are displayed on the LCD screen.

The gold test is very effective in determining whether the item is a karat gold alloy and its possible fineness. This system (gold tester) is not absolute, but a very reliable indicator. It is important to test correctly, associate the results with other facts, and perform other tests if necessary. The electronic gold test is very useful for gold purchases.

What are the differences between the factors and characteristics of the gold tester?

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%.

Gold test method

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

Inspection of metallic materials

Metal materials belonging to metallurgical products, engaged in the production of metal materials, ordering, transportation, use, storage and inspection must be based on a unified technical standards - metallurgical product standards. Personnel engaged in metal materials must master the relevant content of the standard. http://www.gold-testing-machine.com/product/gold-testing-machine-gt-05/ China's metallurgical products use the standard for the national standard (code-named "GB" GB "), the Ministry of the Ministry of Metallurgical Industry Standard" YB ", a machine department standard" JB ", enterprise standard three. (A) packaging inspection according to the type of metal materials, shape, size, accuracy, corrosion may be. 1 . Bulk: no packaging, wiping, block (not afraid of corrosion, not expensive), large steel (large steel, thick steel, rail), pig iron and so on. 2 . Bundle: refers to the smaller size, corrosion has little effect on the use,
