TREK Model341表面电位测试仪说明书

TREK MODEL 341B HIGH-SPEED, HIGH-VOLTAGE ELECTROSTATIC VOLTMETER

  • Measurement Range:
  • Measurement Accuracy:
  • Speed of Response:
  • 0 to ±20 kV DC or peak AC Better than ±0.1% of full scale Less than 200 μs for a 1 kV step
The Trek Model 341B is a DC-stable, precision electrostatic voltmeter for making noncontacting surface voltage measurements. The 341B employs a field-nulling technique that achieves DC stability and high accuracy even if the probe-to-surface spacing changes. This permits measurements of either stationary or moving surfaces without the need to establish fixed spacing to maintain accuracy. The instrument also utilizes a patented probe design that eliminates the need for close tolerance components which significantly improves noise and drift under conditions of high humidity and wide temperature ranges.
Typical Applications Include
  • Charge accumultion monitoring of LCD production processes
  • Monitoring surface potentials in the electrostatic painting process
  • Measuring of electrostatic potentials on polymers, rubber, fabrics and paper
Features and Benefits
  • Superb noise and drift performance
  • Precision voltage monitor output
  • Monitor provides a low voltage replica of the measured electrostatic potential for monitoring purposes or for use as a feedback signal in a closed loop system
  • Easy-to-read LED display
  • Optional probes offer versatility (order separately)
  • Can be operated on a bench top, or with optional hardware, in a standard 19-inch rack
  • NIST-traceable Certificate of Calibration provided with each unit
