Trek 341B [​​​High-Speed, High-Voltage Electrostatic Voltmeter]

​

​​​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
