Established in 1968, TREK, INC. was founded based upon the needs of the electrophotographic industry for highly accurate, stable, cost-effective electrostatic measurement instruments and devices. Beginning with the first noncontacting, DC-stable, electrostatic voltmeter, the Trek Model 300, which quickly became an industry standard, TREK, INC. set the pace for its future growth and reputation as a quality instrument designer and manufacturer. Close association with, and commitment to, the electrophotography industry continues with innovative designs for voltmeters, charger-roller power supplies, and low cost, high performance OEM sensors.
