Dual core metal wrist strap
Product Detailed

with unique designed wrist band can be-direction adjusted ,use conveniently, nicety and quikly.

Description:
ESD Wrist Strap is a basic and widely facility in ESD equipment usage,it is very convenient to operate. It is made up from wrist loop and grounding wire, the wrist loop is contacted with skin directly to form an  electrostatic discharge channel through button connected in series with grounding wire to  take away static electricity from human body. The grounding wire is made of circling wire, space minimum occupied, disengaged adjust operating distance. It can renew after haul straight. Every grounding wire has an safety 1MΩ resistance, it protects operators safety as well as current-sensing devices.

Features:
1.    The resist allergic and high quality stainless steel strap haven't any adverse effect to human body; the wire elasticity is good, renew speedy.
2.   The adjustable wrist band is comfortable for human, haven't mixed any sweat hair, contact very well.
3.   The  transparent blue PU catapult wire can eliminate vision tiredness,elasticity is very good and renew speedy.
4.   The special double channels design has dual role of insurance,  make electrostatic discharge more reliable, greatly reduces the the static electricity damage to the product. 
5.    Full copper fastener and high-force elasticity copper-pin ensure to have a good contact, make the channel of the electrostatic discharge not to have momentary open circuit. 
6.    Can clean and be used in cleaning room  between 10-100 class.
