ESD Measurement Instruments - TEC
ESD Measuring
ESD measuring instruments are the foundation of every compliant EPA (Electrostatic Protected Area): surface resistance meters cover the critical range from 10¹ to 10⁹ Ω, wrist strap testers verify continuous contact resistances below 3.5 x 10⁷ Ω, and electrostatic field meters detect charge potentials from ±1 V up to ±20 kV - all parameters required for certification to IEC 61340-5-1 and ANSI/ESD S20.20. Calibrated test equipment with NIST-traceable measurement accuracy of ±5 % ensures audit-proof documentation across all 44 instruments in this category.
As a specialist distributor for ESD protection technology, esd.equipment stocks handheld meters, bench-top resistance testers, ionisation monitors, combo testers for wrist straps and footwear, as well as data-logging surface resistance kits - sourced from leading manufacturers and fully compliant with DIN EN 61340-5-1, DIN EN 61340-5-2, and IEC 61340-4-1 test procedures.
