RS PRO 821-1264 Surface ESD Tester is a precision instrument designed for quick and accurate measurement of surface resistivity in both industrial and laboratory environments. Powered by a 9 V battery, it features a clear LED display with ten indicators, enabling easy interpretation of resistance levels on material surfaces. Its built-in parallel electrodes allow for rapid testing, while two 4 mm plug sockets and an electrode selector support external electrode connections for point-to-point or earth ground resistance measurements.
The device intelligently switches test voltage from 10 V to 100 V when resistance exceeds 1x10^5 ohms, ensuring reliable readings across wide resistance ranges. The integrated 15-second timer incorporates the electrification period into measurement accuracy, a critical aspect when assessing materials for electrostatic discharge compliance.
This ESD Tester conforms to EN 61340-5-1 standards, making it suitable for establishing EPA (ESD Protected Area) qualifications, equipment installation verification, and periodic audits of ESD protective products in manufacturing, electronics assembly, research laboratories, and other industrial applications.
Built-in parallel electrodes for quick surface resistivity testing. External electrode sockets for point-to-point and earth ground resistance. Automatic voltage adjustment between 10 V and 100 V depending on resistance. 15-second timer for compliance with electrification period requirements.
Compact dimensions tailored for portable use. Complies with international ESD standards EN 61340-5-1. Battery-powered for onsite testing without external power supply.
The RS PRO range is trusted worldwide for high-quality test and measurement instruments that meet rigorous industry standards. This model 821-1264 offers a dependable solution for professionals managing ESD control in electronics manufacturing, quality assurance, and environmental testing.
