The static eliminator can also be called a static electricity removal device. Its principle is as follows. It consists of a high-voltage power supply generator and a discharge electrode (usually made into an ion needle). It ionizes the air into a large number of positive and negative ions through high-voltage corona discharge at the tip, and then uses wind to blow the large number of positive and negative ions onto the surface of the object to neutralize static electricity, or directly brings the static eliminator close to the surface of the object to neutralize static electricity. Static eliminators are mainly divided into the following types: 1. Ac corona products The AC high-voltage generator raises the input voltage of 220V to over 4KV. The discharge electrode alternates between positive and negative voltages at a frequency of 50Hz. A strong electric field is generated between the discharge electrode and the grounding electrode, ionizing air molecules and alternately generating positive and negative ions at the tip of the discharge electrode. When the surface of a charged object has a positive potential, negative ions will neutralize it; conversely, if the surface has a negative potential, positive ions will neutralize it. Ac corona products must be grounded to function properly, but some positive and negative ions will be directed to the ground due to grounding. However, the structure is simple and the balance of positive and negative ions is good. 2. Dc corona products The DC high-voltage generator raises the 220V input voltage and outputs positive and negative voltages respectively. A strong electric field is generated between the positive and negative discharge electrodes. Air molecules are ionized, and positive ions are produced at the tip of the positive discharge electrode and negative ions at the tip of the negative discharge electrode. Both positive and negative ions are generated simultaneously to neutralize the static electricity on the surface of the object. When the surface of a charged object has a positive potential, negative ions will neutralize it; conversely, if the surface has a negative potential, positive ions will neutralize it. Dc corona products can generate positive and negative ions without grounding. There are sufficient positive and negative ions acting on the surface of objects, and the speed of neutralizing static electricity is very rapid

For a closed surface, the difference between the number of electric field lines passing through the surface and the number passing through it is directly proportional to the algebraic sum of the charges and quantities contained within the surface. This is the well-known Gauss's theorem concerning electrostatic fields.

The performance features of the testing instrument include Chinese display and a user-friendly interface: All data, status and operation prompts are displayed in Chinese, with no symbols or codes defined by the manufacturer itself. Simple menu structure and text-based human-table dialogue: It is clearer and more convenient to use. Just follow the prompts on the screen to operate. Simultaneous display of multiple parameters: Conductivity, output current, temperature, time and status are displayed simultaneously.

The electrostatic tester is specifically designed for the handling of static electricity and should be kept away from water, oil, solvents and other conductive contaminants. Exposure to such pollutants will cause electrical insulation faults in the products. Be especially careful to ensure that no dew forms in the environment. The electrostatic tester should be stored and used in an environment with a humidity of less than 60%.

Product features: It can test the anti-static function of anti-static wrist straps and anti-static shoes simultaneously. It is equipped with computer software that can be connected to a computer to record the test data and time conditions of each staff member. The software can store up to 5,000 workers' test records

1. Rotate the speed regulator switch clockwise until the indicator light is on, which will turn on the fan and generate an ionic airflow. To increase the fan speed, you can rotate the speed regulator switch clockwise. When the position is set to "off", the indicator light goes out, indicating that the ion fan is shut down. To adjust the airflow direction, loosen the plum blossom screws on the bracket, tilt the machine body to adjust the up and down position, and then tighten the bracket screws after adjustment. To clean the ion emitter, rotate the handle of the cleaning head clockwise until it stops, and then repeat the rotation until it is thoroughly cleaned.
