• Used with resistive loop technology continuous monitor, continuously verifies the proper resistance to ground of the operator
• Coil cord with molded 1 Megohm current limiting resistor on both ground paths to protect user from shock due to inadvertent contact with line voltage
• 28 gauge wire
• 3.5mm phono plug connector
• Patented (6,052,053 and 6,205,408) dual wire technology
• Superior warranty - See details of 1 year Limited Warranty

What the ESD Association says about testing wrist straps:
Per ESD Handbook TR20.20 section 5.3.9.1 Wrist Strap Checkers - “Wrist strap checkers have historically been the primary tool for testing the operation of the wrist strap system including, the wristband, grounding cord and most importantly, the electrical integrity of the contact between the wristband and the wearer. Wrist strap checkers measure the resistance of the entire system.”
