The 8501 is a small lightweight static dissipative Portable Field Service Kit that offers the same level of static control as the full-sized 3M? field service kit 8501, yet is small enough to fit in a shirt pocket. It is designed for electrostatic protection of static-sensitive components during field service calls. It is designed to quickly and reliably remove any static charge on the technician and to provide a static-free surface upon which to lay parts. The static-dissipative work surface reduces the potential for sparking and shorting that exists with highly conductive mats and minimizes charge drainage from battery packs. For added safety, cotton trim covers all edges of the mat.
