Determines the smallest quantity of energy, as a capacitive or inductive spark discharge, required to ignite a powder. Resulting data can be used to assess risks in processing and handling industrial powders.


  • Voltage and capacitance can be controlled in fine increments
  • Arc gaps can be manually adjusted for researching alternative gaps being more conducive to ignition
  • Delivers results to ASTM E2019-03 and IEC 61241-2-3 and EN standards
  • Wide range of available accessories
