LCD voltmeter 876, 884

portableelectrostatic

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-tomeasured 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 CE compliant
