ESD Measurement Instruments Our ESD measurement instruments deliver not only high accuracy but also high confidence. Trek charged-plate monitors (see photo) help with ionizer setup, calibration and auditing processes. Model 158A Charged-Plate Monitor Trek hand-held electrostatic voltmeters and portable electrostatic voltmeters (see table) are easy-to-use and provide accurate surface voltage measurements throughout manufacturing processes, whether in semiconductor, hard disk drive, flat panel display or other highly sensitive environments. TREK, INC. High-Voltage Power Amplifiers ¨ Power Supplies ¨ Electrostatic Voltmeters ¨ ESD Instruments TREK, INC. is a privately-held company (est. 1968) with technical and application expertise in electrostatics and high-voltage power amplification. Trek's products are used by Original Equipment Manufacturers (OEMs) to enhance operational precision of their equipment and by researchers to enable innovation around the world in electrostatics, materials, nanotechnology, piezoelectrics and plasmas. Trek's ESD audit kit (see photo) includes an electrostatic field meter (with charger and charge plate) and surface resistance meter in a compact carrying case; it provides versatility and utility for electrostatic field measurements, air ionizer verification, testing of floor materials and systems, and resistance measurements. Model 511/1501 ESD Audit Kit Trek's surface resistance/resistivity meters (see photo) deliver precise surface resistance measurements on virtually any conductive, dissipative or insulative material. These instruments enable quick and accurate checks on dissipative floors, work surfaces, table mats, and other static-controlled materials to insure that static charge is safely dissipated to ground. TREK, INC. headquarters and manufacturing are now located in a 40,000 sq ft facility in Lockport, NY Engineering and R&D are housed nearby in the Trek Technology Center Model 152-1 Surface Resistance Meter Applications Include: ¨ Static charge monitoring ¨ Material dissipation testing ¨ Measurements for ESD control Some of Trek’s ESD Measurement Instruments Model Measurement Range (DC or Peak AC) Measurement Accuracy (full scale) Probe-to-Surface Separation Distance Cable Length Charge accumulation in LCD manufacturing, static charge in Semiconductor manufacturing Static charge evaluation, Semiconductor, LCD, electronic assembly Measurements in difficult to reach areas, battery or line operation, records temperature and humidity 3 meter (10 ft) Static charge evaluation, Semiconductor, LCD, electronic assembly Trek designs and manufactures high-voltage amplifiers, piezo drivers, power supplies & generators and high performance electrostatic measurement instruments — including electrostatic sensors and detectors, electrostatic discharge (ESD) instruments, electrostatic voltmeters, charged plate monitors, and surface resistance/resistivity meters — to meet the high performance needs of the global marketplace.
