Best Quality High Accuracy and Stability Phase Meter ETCR4100 Double Clamp Digital Phase Meter
PRODUCT DESCRIPTION
Product Description
The etcr4100 double clamp digital phase meter is a well-developed meter specifically designed for field testing, featuring high accuracy, high stability, low power consumption, easiness to use and so on. It can directly measure phases between two voltages, two currents and phase between the voltage and current; In addition, it can also be used to distinguish three-phase sequence, transformer wiring group, inductive and capacitive circuits, test Second circuit and bus differential protection systems, read the phase relationship between cts of the differential protection, etc.
The etcr4100 double clamp digital phase meter has a large LCD screen displaying words as high as 40mm against a blue backlight, and looks exquisite and comfortable.
The etcr4100 double clamp digital phase meter applies to electricpower, petroleum chemical industry, metallurgy, railway, and meteorology, industrial and mining enterprises, scientific research institutions, measurement sector and so on.
