How to remove static electricity in electronic balance?

It is very important to weigh experimental instruments accurately and accurately, but there are often some small factors that affect the accuracy of weighing.

Six tips for eliminating static electric interference in electronic days keep you away from static electricity and achieve accurate weighing.

For laboratory researchers, it is very important to weigh experimental instruments accurately and accurately, but there are often some small factors that affect the accuracy of weighing. Electronic balance is based on the principle of electromagnetic force balance to realize weighing. Although the accuracy and sensitivity of measurement are higher than those of traditional mechanical precision balance, because this balance is easily affected by external temperature and electromagnetic environment, we should pay attention to some details when using it, so that we can improve its weighing accuracy.

Electrostatic phenomena occur in the use of electronic balance is more troublesome, such as: ceramics, plastics, glass and so on will have electrostatic charges, the magnetic field between the sample and the electronic balance will produce a weighing error of 1g, so when we weigh in milligrams or smaller, the influence of electrostatic will increase.

Six tips for eliminating static electric interference in electronic days keep you away from static electricity and achieve accurate weighing.

1. The most direct way to avoid static electricity is to increase humidity, which is best at about 70%.

2. If the said article has static electricity, remove it and weigh it again.

3. The static electricity on the operator can be removed by touching the wall before the user uses the balance.

4. In addition to maintaining the humidity of the environment in which the electronic balance is used, the ground wire of the electronic balance should be well connected, which can effectively avoid the generation of static electricity.

5. In addition to the above methods of eliminating static electricity in Cydoris electronic day, some users use metal sample tanks to eliminate static electricity quickly. But some users can not choose weighing containers, such as filter paper weighing users, they can use special weighing chambers, such as: semi-high weighing chamber, special metal, weighing table, so as to eliminate static electricity and reduce the impact of air flow.

6. Use static eliminator to eliminate static electricity, so as to ensure that the weighing items are insulated.
