Electrostatic Force Microscope (EFM)
Trek's Model 1100TN EFM enables voltage distribution measurements with very high spatial resolution – better than 10 µm – well beyond the capability of typical electrostatic voltmeters.
Charge to Mass Ratio Test System
Trek's Model 212HS is a unique small and portable Q/m analyzer which utilizes the “draw-off” toner transfer method to yield repeatable high accuracy toner charge measurements.
Trek provides probes, ion collecting plates,
racks, cables, adapters and other accessories
for its electrostatic voltmeters, surface resistance
charged plate monitors, and HV amplifiers.
