Overview
The Trek® 370 employs an electrostatic field-nulling technique to achieve high DC stability and high measurement accuracy — regardless of probe-to-measured surface spacing changes. This permits highly accurate stationary or moving-surface measurement without fixed-spacing. An automatic gain feature eliminates the need for manual adjustment when changing probes or probe-to-surface distance. A precision voltage monitor provides low voltage representation of the measured electrostatic voltage for external monitoring purposes, or use as a feedback signal in a closed-loop system.
Benefits
- Eliminate the need for manual adjustment with automatic gain feature
- Operate on a benchtop or, with optional hardware, in a standard 19-inch rack
- Utilize one-step, push-button zeroing
Features
- Automatic gain
