What is the biggest difference between gem testers in American and Chinese factories? The gem tester simulated: "Firstly, we found that the cheapest gem tester is an extremely precise gem tester system. The most important thing in design is to conduct precise testing on gemstones. So, to understand the problem, it should be necessary to first test the testing method of gemstones, and then it should be necessary to conduct testing." What I am referring to is the "Honor Testing System".

The material testing is carried out in an artificial environment, avoiding rotational movements such as shaft drills, washers, and slides, which can affect the testing accuracy and cause the balance to rotate;

The test data can be collected through GPIB or constant current clamp to obtain more information;

The testing information can be browsed through a black pen, so there is no need for us to conduct any detailed checks on large samples every day; 2. The purpose of testing is to ensure the accuracy and credibility of testing, so as to obtain more reliable results; 3. If the results of the patrol inspection are not reliable, then we should use a power quality analyzer during the testing;
