The Trek Model 341B is a DC stable, precision electrostatic voltmeter for making noncontacting surface voltage measurements in the range of 0 to 20kV DC or peak AC. Research and industrial applications include charge accumulation monitoring of the LCD production process, monitoring surface potentials in the electrostatic painting process, research and development in the electrophotographic process and measuring electrostatic potentials on polymer,rubber,fabrics and paper.
Measurement Range:0~±20KV
resolution：1V
Accuracy: Better than 0.1% of full scale
Speed of Response:Less than 200us for a 1kV step change
