and high quality Double circuit electronic, anti-friction. Loop length can be adjusted. Easy to use and flexible, and does not dust, can be used for more than 100 Cleanroom environment. Mainly for the production line and static is high individuals within the of activities of production and easy to static electricity generated in their daily working lives high electrostatic potential Use of "point discharge" principle, to achieve electrostatic and release. Application: Can be used as due to the improper personnel touch power, cause instantaneous import a number of static charges, in and less than complete, can be provided by the water molecules with screw outside air through and (for the effects of discharge), the static electricity effectively eliminate, and electrostatic discharge (static voltage balance). Use this screw for potential zero 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 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 cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
