This anti-static tool made of chrome-plated steel, copper conductor, high voltage resistance. It can be used to discharge the electrostatic on objects around you in daily life, door handles, office equipment, house hardware, etc. As the form of a keychain, it is convenient to use and easy to carry. It has a secondary discharge function, which makes it remove the static as quickly as 0.2 seconds. When to release static, the LED light will shine, can only see the flash in the darkness. Static electricity will continue to accumulate in daily activities, so it is better to discharge static electricity every time before touching a metal part or other conductors. Proper use of this anti-static keychain will help you get rid of static shock in the dry winter. About Electrostatic Static electricity can cause upright hair, dust adsorption, electrostatic sensitive devices breakdown, etc. It is most likely to be generated in a dry environment, such as the friction of fiber fabrics, seats, etc. It is impossible to eliminate of static electricity by one use because everyones body resistance and the generated static voltage is different. Static electricity will continue to accumulate in daily activities, therefore it is necessary to use this anti-static keychain multiple times. Applications -This product can be used to discharge the electrostatic on objects around you in daily life(e.g. door handles, doorknobs, office equipment, etc.) -Engaged in the work of electronic products, discharge static electricity to prevent contacted electrical components from being broken down. -Wear it can eliminate static electricity generated by the human body, escape from shock due to the discharge of static electricity. How to use 1. Hold the keychain end of the device. 2. Touch the tip to the conductors (metal parts and others). 3. The LED light may not flash when the static is weak. You may hear a "POP" sound when discharging weak static. 4. Attention: The anti-static keychain cannot eliminate static effectively by touching clothes directly, it must be contacting conductors to release static electricity.
