The Trek Model 876 (±2kV) and Model 884 (±20kV) Hand-Held Electrostatic Voltmeters provide accurate, noncontacting measurements of electrostatic surface voltage for ESD applications in either ionized or non-ionized environments. These two voltmeters utilize a measurement technique that overcomes the disadvantage of the typical hand-held field-meter by providing surface voltage measurements which are essentially independent of the sensor probe-to-measured surface spacing. Model 876 Key Specifications . Measurement Range: 0 to ±2 kV DC . Measurement Accuracy: Better than ±5% of full scale over the entire recommended probe-to-surface separation range of 5 mm to 25 mm Model 884 Key Specifications . Measurement Range: 0 to ±20 kV DC . Measurement Accuracy: Better than ±5% of full scale over the entire recommended probe-to-surface separation range of 30 mm to 60 mm Typical Applications Include . Measurement of electrostatic surface charge build up • Manufacturing processes • Electronic assembly testing • Semiconductor material testing • Dissipative material testing • Automotive electronics testing • ESD Auditing and troubleshooting Features and Benefits • Accurately measures surface voltage at a wide range of spacings • No need to maintain a fixed spacing • Chopper stabilized for drift-free operation in ionized environments • NIST-traceable Certificate of Calibration provided with each unit . compliant TREK, INC. • 190 Walnut Street • Lockport, NY 14094 • USA • 800-FOR TREK 716-438-7555 • 716-201-1804 (fax) • www.trekinc.com • sales@tr
