掌上型靜電電壓表TREK 520

掌上型靜電電壓表TREK 520

Trek Model 520/523手持式靜電電壓表可以實現高精度非接觸表面靜電電壓測量,并且不受探頭到被測表面距離及離子風影響;Trek Model 884/876 手持式靜電電壓表具有一個電纜延伸的緊湊的探頭,這種設計探頭可以達到在一些小空間內的高靈敏度測量.延長電纜的長度為6英尺,這樣的長度可以實現更為靈活的測量應用.

Model 520 Series HAND-HELD Electrostatic Voltmeter
The Model 520 Series includes the Model 520 and Model 523.
The Trek Model 520 Hand-Held Electrostatic Voltmeter (ESVM)
Series products provide accurate, noncontacting measurements
of electrostatic surface voltage for ESD applications in
either ionized or non-ionized environments. Industrial
applications include measuring charge accumulation in the
 LCD manufacturing process or measuring static charge in
semiconductor production. The Model 520 series ESVMs utilize
 a new measurement technique that overcomes the disadvantage
of the typical hand-held fieldmeter by providing surface
voltage measurements which are essentially independent of the
 sensor probe-to-measured surface spacing.
Model 520-1 ESVM
Over a spacing range of 5 mm to 25 mm, the 520 voltmeter
provides better than a 5% voltage measurement accuracy, while
the typical fieldmeter provides a voltage measurement error in
 excess of 50%. An optional voltage monitor output is available
 (Model 520-2). 
Model 523 ESVM
Over a spacing range of 30 mm to 60 mm, the 523 voltmeter
provides greater than a 5% voltage measurement accuracy,
while the typical fieldmeter provides a voltage measurement
 error in excess of 50%. 
The 520 series provides a measurement system which complies
with standardized calibration equipment traceable to the
National Institute of Standards and Technology. The 520 series
 hand-held voltmeters employ a slender sensor probe design
that provides flexibility to make measurements in many
locations which are impossible to reach using the large,
bulky sensing surfaces of the typical hand-held fieldmeter.
The slender design also allows for higher spatial resolution
capability by allowing the measurement of small surface areas.
 A "hold" pushbutton retains the displayed measured voltage
value for recording purposes.
