TREK, INC. has decades of expertise in its core competencies:

  • High-voltage power amplification
  • Electrostatic measurement

The company’s high-voltage amplifiers employ unique and proprietary circuitry to produce a closed-loop amplifier system which features exceptional DC stability and excellent wideband performance characteristics for driving capacitive loads. Featuring all-solid-state construction, Trek amplifiers are fully protected against arc-over and operation into short circuits.


Trek’s novel non-contacting electrostatic voltmeter designs circumvent the charge transfer issues associated with traditional contacting designs. The company also offers an ultra-high impedance technology (Infinitron®) to enable surface contact measurements with virtually zero charge transfer.

Trek also offers a line of ESD sensors & monitors for electrostatic discharge applications.

Trek designs and manufactures its products for demanding applications in research and industry. In industry, Trek’s products are incorporated by Original Equipment Manufacturers (OEMs) to enhance the precision and reliability of high-end capital equipment such as that found in semiconductor manufacturing, photovoltaic production and electrophotography processes. Trek’s custom OEM design capabilities provide a unique advantage compared to other suppliers in this market.

In R&D, Trek’s products enable research and innovation in dielectrics, electrostatics, materials, piezos and plasmas. Research organizations use Trek products for studies regarding accelerator mass spectrometers, dielectric barrier discharge (DBD), electroactive polymers (EAP), electrocoalescence, electrohydrodynamics (EHD), electroluminescence, electron beam ion traps (EBIT), electron beam ion sources (EBIS), electro-optic modulation, electrophoretic display, electrorheological (ER) materials, electrospinning, electrospraying, electrostatic chucks, electrostatic precipitation, ferroelectric poling, fluidized beds, Johnsen-Rahbek wafer clamping, ion beam steering & deflection, microelectromechanical systems (MEMS), microfluidics, nanotechnology, non-thermal plasma chemistry, partial discharge dielectric tests, piezoelectrics, precision manufacturing, smart materials, space radiation and vibration dampening.
