Description
Overview
GAOTek comprehensive tester has multifunction digital safety testing instrument, designed with a combination of large-scale integrated analog & digital circuits and micro-processor chip. It mainly measures RCD, line or loop impedance, continuity, insulation resistance, DC and AC voltage, phase sequence, featuring versatile functionality, higher accuracy, stable performance and ease of use. The instrument is widely used to measure RCD, insulation and earth connections for various equipment, and an ideal tool for testing, inspection and maintenance badly needed for various electric devices and RCDs.
