High-Sensitivity, DC Stable, Precision Electrostatic Voltmeter
Advanced Energy's Trek P0865 electrostatic voltmeter is ideal for making non-contacting surface voltage measurements in the range of 0 to ±10 kV DC or peak AC. It features a field-nulling technique that enables high DC stability and accuracy.
- Response Time: Less than 200 ms for a 1 kV step
- Measurement Range: ±10 kV DC or peak AC
- Measurement Accuracy: Better than ±0.1% of full-scale
- Technical Specs
- Service & Support
The Trek® P0865 employs a field-nulling technique for non-contacting voltage measurement. It achieves DC stability and high accuracy even if the probe-to-surface spacing changes. This permits accurate measurements of either stationary or moving surfaces without the need for fixed spacing.
A precision voltage monitor provides a low-voltage replica of the measured electrostatic potential for monitoring, or use as a feedback signal in a closed-loop system. And probe assembly includes a sensitive electrode and preamplifier, which is driven to the same potential as the measured value to eliminate arcing therebetween. A three-meter cable permits remote probe positioning.
- Utilize patented probe design to eliminate the need for close tolerance components
- Improve noise and drift performance
- Operate on a benchtop, or, with optional software, in a standard 19-inch rack
- Use for various research and industrial applications
- Accurately measure stationary or moving surfaces
- Precision voltage monitor output
- Zero control for offset nulling
- Easy-to-read LED display
- High temperature probes available
- Field nulling technique
