Trek Model 158A
Charged Plate Monitor

  • Monitored Voltage Range:
  • Bandwidth (-3dB) :
  • Decay Mode Thresholds:
  • 0 to ±1100 V DC or peak AC
    DC to 80 Hz
    Programmable from 1 to ±1000 V in 1V

The Trek Model 158A Charged-Plate Monitor is the premier instrument to evaluate the performance of air ionization systems. It features a user-friendly large 7 inch screen that is active through either touch-screen control or corresponding function keys. The compact design supports superior data collection and data storage capability. The data is displayed in color and may be stored internally or can be easily transferred to a USB flash drive or other USB device.
A charged-plate assembly is required and is sold separately (6 inch
charged-plate shown).

Typical Applications Include
  • Performance evaluation of air ionization systems
  • ESD Test Equipment
  • ESD Audit Equipment
