Stable isotopes are naturally occurring isotopes that cannot be detected by current technical means. They are widely used in research and production fields such as nuclear power industry, medicine, food, agriculture, ecology, and geology.
The stable boron isotopes developed and produced by ZSEM mainly include boron 10 acid, boron 11, boron trifluoride complexes, etc., which can be used as Nuclear Power Safety Materials, semiconductor chip manufacturing process materials, and biopharmaceuticals.

In China, the vastness of the land, the longitude and latitude, and the latitude and longitude are very different. There are also certain impacts on the platform scales in different places. In addition, there are n domestic loadometer manufacturers in the country, and there are differences in the scales produced. At this time, a fixed institution is needed. To check this accuracy, of course, this institution needs a certain degree of authority, and this time it was born - a measurement institute. Basically, each area has its own national unit, and one of the tasks it is responsible for is the verification and correction of the ground scale.
The scale test can be roughly divided into:
1. Turn down the division value (some places can not adjust)
2. Use a few tons of weight presser foot (tonnage as appropriate), to see if there is a foot difference, and some need to adjust over 3. After processing the above, directly load the range weights to see if the weight is accurate, whether in Within the allowable error range. 4. If there is no problem, you can directly give the certificate to the general industry. The measurement of the weighbridge is once a year. Some trade-related industries are almost twice a year, according to their own Ask for a choice, of course, the above costs are the customers themselves.

Analysis of the Verification Regulations for 1 Ton Electronic Platform Scale in Shanghai
The tool used to measure large vehicles and large-tonnage goods, the vehicle electronic platform scale or the truck scale, can be called the platform scale from 10t up to 200t, which is commonly called ground scale. Of course, within this scope, we basically meet the individual exceptions of domestic industries. With the increasingly refined industrial level, the demand for this is getting bigger and more styling. However, no matter what kind of change, in the final analysis, it is a word - accurate. Once the scale is not allowed, other subsidiary functions are useless, and there is no significance.
