Ionizers hero

EF-S1 electrostatic sensor

Constant monitoring of static charges on production lines.


  • Maintains and regulates product quality by preventing damage from static electricity
    Static electricity that can build up in various places along a process line can be monitored constantly so that abnormalities can be prevented before they occur, ensuring quality.
  • Reduces time for ionizer inspections
    The de-ionizing effectiveness of ionizers can be understood in real-time so that things such as ionizer damage and the replacement period for worn components can be checked objectively, reducing the time required for inspection and testing.
