ZXDN-306 220V 380V Three Phase Energy Meter Test Multimeter Test Bench

ZXDN-306 three-phase multi-function meter inspection device is our company's requirements according to relevant national standards and regulations. Based on the accumulation of more than ten years of production experience of the three-phase program-controlled electric energy meter verification device, the electronic program-controlled three-phase electric energy meter verification device has been carefully developed. It is based on different types of calibration devices developed and produced by different three-phase energy meters; it is suitable for the inspection of various single-phase three-phase energy meters (including sinusoidal reactive power meters) of level 0.2 and below. Craftsmanship, complete functions and excellent performance will definitely be favored by you.
