Description

Overview

GAOTek electrical handheld power has a quality analyzer with 32 g data logger. This product is easy to wire, it can operate directly to the line under test under the circumstances that the power grid without interrupt, multi-range current switching and based on actual demand, the different range of current clamp can be replaced to improve measurement accuracy.
