3M 740 Wrist Strap and Shoe Tester Power Supply not included,This testing device is designed to verify the effectiveness of personal grounding equipment such as wrist straps and conductive footwear used in electrostatic discharge (ESD) control programs. By measuring the electrical resistance between the operator and ground, it ensures that ESD protective devices are functioning within acceptable limits, helping to prevent static-related damage to sensitive electronics. The tester features a clear display and simple operation, allowing quick pass/fail checks before entering ESD-protected areas. It can test wrist straps via a dedicated connection point and shoes via a footplate, with results displayed almost instantly. The device operates using an external power source, which must be supplied separately. Its compact, robust design makes it suitable for mounting at entry points to cleanrooms, assembly lines, or repair facilities. Reliable performance, ease of use, and compliance with ESD standards make it a key component in maintaining product quality and protecting electronic components.
