Description: 1.The wristband is woven with a soft, flexible material with conductive yarns. The static electricity is exported quickly and the belt is adjustable in size for wearing. 2.The wristband buckle shell is made of PU material, and the button combination can be separated at will, which is convenient and practical. 3.The end of the end is made of stainless steel alligator clips, easy to clamp the anti-static ground wire, easy to operate, practical. 4.The coiled wire is made of PU material, which has good elasticity and can be stretched to 1.7M. It contains 4-core copper platinum wire and 1M ohm resistor. 5.The hand ring can remove the static electricity from the human body to the grounding wire within 0.1 seconds before the static electricity mar the electronic product, and use the wristband to ground the operator. 6.This product is suitable for the environment with static electricity, such as factory workshop, electronic maintenance, dust-free workshop, etc. Working Principle: The human skin is in direct contact with the conductive material on the wrist strap. When the wrist strap is grounded, the static electricity generated by the movement of the human body is quickly released through the grounding system, the static electricity of the human body is guided to the earth through the wrist strap and the grounding wire.
