new and high quality Double circuit electronic, anti-friction. Loop length can be adjusted. Easy to use and flexible, 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 electricity generated in their daily working lives high electrostatic potential Use of "point discharge" principle, to achieve electrostatic collection and release. Application: Can be used as due to the improper personnel touch power, cause instantaneous import a large number of static charges, in ion and less than complete, can be provided by the water molecules with screw outside air through ion and (for the effects of discharge), the static electricity effectively , 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 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 cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
