Feature 1[Quick Elimination] Touching the ball for more than 3 second can effectively eliminate static electricity in the body, with high sensitivity and quick response. 2[Safety Use] This static releaser can extend the electrostatic discharge time, reduce the instantaneous discharge energy, ensures safety. 3[Long Lasting] This human body static elimination ball has explosion proof and anti corrosive functions, can be safely used for a long time. 4[Voice Broadcast] The human body electrostatic discharge device has a voice broadcasting function, increases convenience. 5[Wide Application] Suitable for chemical, metallurgical, petroleum, fireworks, computer rooms, high end hotels, hotels, office buildings, etc.Item Type: Human Body Electrostatic ReleaserMaterial: 304 stainless steel, PEPower Supply Method: 1 x lithium ion battery 1500mAh (built in)Ball Diameter: Approx. 88mm/3.46inBall Wall Thickness: Approx. 1.5mm/0.06inVertical Pole Diameter: Approx. 32mm/1.26inVertical Pole Wall Thickness: Approx. 1.5mm/0.06inChassis Wall Thickness: Approx. 3.5mm/0.14inChassis Diameter: Approx. 120mm/4.72inOverall Height: Approx. 310mm/12.2inInstallation and debugging of static electrical appliances:Fix the base of the static releaser well, and connect the grounding wire to the grounding grid or pile. If the installation site is not equipped with a grounding grid or grounding pile, a metal rod can be driven into the ground to a depth of about 30cm, and then the grounding wire can be connected to the metal rod for use. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Human Body Electrostatic Releaser3 x Anchor1 Set x Identification StickerNote1. Please ensure that the human body electrostatic discharge device (anti human static device) is grounded reliably and regularly inspected;2. There is an error in size;3. The voice broadcast is in Chinese and cannot be adjusted, please do not mind (the broadcast sequence is: static electricity is being released, static discharge completed, safe)
