ESD Measuring - TEC
ESD equipment
ESD measuring and test equipment covers the full verification chain required by IEC 61340-5-1 and ANSI/ESD S20.20: surface resistance measurement from 10¹ to 10¹² Ω, electrostatic field detection down to ±1 V/cm, wrist strap verification within the 750 kΩ-35 MΩ acceptance window, and continuous workstation monitoring with alarm thresholds set to <100 V. Instruments in this category also address relative humidity logging (target range 40-60 % RH per IEC 61340-5-1 Annex C) and walking-test body-voltage measurements up to ±20 kV, enabling a full EPA audit with traceable documentation.
As a specialist distributor for ESD protection equipment, esd.equipment supplies 234 test and measurement instruments from leading manufacturers - covering every instrument class needed to qualify, audit, and maintain an electrostatic protected area to current norm requirements. Calibration services and replacement probes ensure long-term traceability in accordance with DIN EN ISO/IEC 17025.
