Trek Models 520 and 523

下载文件 产品查询

The Trek® 520 (±2 kV) and Trek 523 (±20kV) hand held electrostatic voltmeters that 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.

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

Specifications:

TK 520
 Measurement Range   0 to ±2 kV DC
 Accuracy   Better than ±5% of full scale over the entire recommended probe-to-surface separation range

TK 523
 Measurement Range   0 to ±2 kV DC
 Accuracy   Better than ±5% of full scale over the entire recommended probe-to-surface separation range
