Trek has introduced the Model 325 electrostatic voltmeter, an ultra-sensitive instrument suitable for noncontacting electrostatic voltage measurement and monitoring in applications within high-tech, ...

The Model 325 electrostatic voltmeter from Trek covers a measurement range from millivolts to ±40 V over probe-to-surface distances of 0.2 mm to 2 mm. The instrument also offers a sensitivity of 1 mV, ...

Particularly useful in design of electrophotographic devices such as faxes and copiers, the model 400 electrostatic voltmeter is accurate to better than ± 0.1% of reading ± 1.0 V. With a dual-chopper ...

E. H. W. BANNER (J. Inst. Elec. Eng., 89, Pt. 2, No. 10 ; Aug., 1942) describes an electrostatic voltmeter type of instrument connected to give readings proportional to the r.m.s. voltage and designed ...
