Brand new and high quality Double circuit electronic, anti-friction. Loop length can be adjusted. Easy to and flexible, long life and does not produce dust, can be used for more than 100 Cleanroom environment. Mainly for the production line staff and static index is high individuals within the scope of activities of production and easy to produce static generated in their daily working lives high electrostatic potential of " discharge" principle, to achieve electrostatic collection and release. Application: Can be used as due to the improper personnel touch , instantaneous import a number of static charges, in and less than complete, can be provided by the water molecules with screw outside through and (for the effects of discharge), the static effectively eliminate, and electrostatic discharge (static voltage balance). this screw for potential function (just put the screws can be touching the ground). Main parts: Adopt ABS plastic material synthesis; Material:plastic Wrist ring: Anti-static yarn weaving Color:Wine red Size:180cm * 2cm * 1cm Surface resistance: less than equal 103Ohm Electrostatic discharge time: Less than 0.1s Cable length: Adjustable Package Included: 1 x Anti-static Wrist Strap Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
