ESD Simulator ESS-B3011A/GT-30RA

Electrostatic Discharge Simulator ESS-B3011A/GT-30RA

EN/IEC 61000-4-2 Ed2 & ISO 10605 Ed2 Compliant 

Cost-oriented Basic ESD simulator 

ESD Simulator Model ESS-B3011


(Note: Discharge gun stand is an optional accessory.)




  • EN/IEC 61000-4-2 Ed2 Compliant (B3011A)
  • ISO 10605 Ed2 Compliant (B3011A) (Note: Optional gun head and CR units are required.)
