ESD Wrist Strap & Monitor Testers

Verification tools that prove your grounding system is actually working.

Wrist straps and heel grounders only protect static-sensitive devices if they are making good electrical contact and properly connected to ground. ESD testers and continuous monitors are how you verify and document that protection. They measure the resistance of the person–strap–cord–ground path against defined limits (typically per ANSI/ESD S20.20 / IEC 61340-5-1) so you can catch broken cords, worn bands, bad connections, or wrong footwear before operators touch high-value electronics.

In practice, most programs require operators to test their wrist straps and/or heel grounders at the start of each shift using a pass/fail tester, with results logged or enforced via access control. Continuous monitors go further by watching the grounding path in real time at the workstation, alarming immediately if a connection fails during the job. Together, these devices turn ESD control from an assumption into a measured, auditable control point.
