Item Type: Human Body Electrostatic Releaser Material: 304 stainless steel, PE Power Supply Method: 1 x lithium ion battery 1500mAh (built in) Ball Diameter: Approx. 88mm or 3.46in Ball Wall Thickness: Approx. 1.5mm or 0.06in Vertical Pole Diameter: Approx. 32mm or 1.26in Vertical Pole Wall Thickness: Approx. 1.5mm or 0.06in Chassis Wall Thickness: Approx. 3.5mm or 0.14in Chassis Diameter: Approx. 120mm or 4.72in Overall Height: Approx. 310mm or 12.2in Installation 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. 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.1. 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) 1 x Human Body Electrostatic Releaser 3 x Anchor 1 Set x Identification Sticker
