Voltmeter Probes

A sample of our probes are listed below. Please scroll the page to find the probe that interests you. For other models or additional assistance, please contact us.


The patented design of Trek probes provide the largest possible signal strength to reduce noise and drift, and to maintain optimum performance at wider probe-to-surface distances. In Trek probes, the electrode is located on a vibrating reed. This places the electrode in motion, in the aperture, close to the surface for maximum signal strength. Trek probe designs eliminate the need for close-tolerance components. This significantly improves noise and drift performance under varying temperatures, high humidity, and in the presence of contaminating particulates.
