NRM Series High Voltage Probes

NRM series high-voltage probes are used in the development and testing of DC high-voltage power supplies X-ray power supplies electrostatic precipitator power supplies medical power supplies CT or PECT drive power supplies or various pulse high-voltage power supplies. This high-voltage probe not only can meet the most demanding space electric field interference environment but it can also be used under special temperature and environment. It has been tested and approved by many universities and laboratories in China. Some users of this series of high-voltage probes include the Strong Magnetic Field Center of Huazhong University of Science and Technology North China Electric Power University Wuhan University of Technology Schneider Electric (China) Co. Ltd. Southwest Institute of Physics for Nuclear Industry and other units.
