Description

Technical Field

[0002] The static tester, also known as the static tester, is a non-contact portable static field tester. The tester is also equipped with an ion balance measurement board for periodic calibration of the ion balance within the range of ±200V. It is mainly used to determine the static properties of textile raw materials and finished products under laboratory conditions. It can also be used to determine the static properties of other sheet and plate materials such as paper, rubber, plastic, composite panels, etc. The main body of the instrument consists of a corona discharge device, a probe and a detection system. It uses a given high-voltage electric field to discharge the test sample at a fixed time to make the sample induce static electricity, thereby detecting the size of the static electricity, the half-life of the static voltage, and the amount of static electricity residue to determine the static properties of the test sample. When the static tester is used for static electricity testing of an object, if it is used directly by hand, it will make it difficult to grasp the distance from the workpiece being tested, and because the tester also carries a certain amount of static electricity, it will cause a certain amount of static electricity. Interference affects the accuracy of the results. Therefore, in an environment where precise testing is required, an electrostatic tester is generally used with a workbench with a fixture to cooperate with the test. The electrostatic tester is fixed to the workbench, and the fixture fixes the workpiece, which is convenient for adjusting the distance and avoiding electrostatic interference from personnel.
