The Static Solutions SP-102 Ground Checker w/Ohm-Stat WS-1020 Wrist Strap grounds a user wearing an ESD wrist strap and analyzes the grounding correctness of a single operator through a 3-prong 120v power receptacle. This unit provides proper grounding while preventing new charges from accumulating, and is an easy-to-use field service tool. The SP-102 consists of a WS-1020 Ohm-Stat Elastic Adjustable Wrist Strap that plugs in easily to the SP-101 circuit tester/grounding plug. The SP-101 tester provides a hard ground to an electrical system to drain charges away from user and is made from a tough impact-resistant polymer that is ultrasonically welded for added protection against water. It also features high-visibility, long-life LED indicator lights with wrap-around lenses to supply visual proof of a correct ground, or any common ground faults, at any angle.
