NRM Series High Voltage Probes

The NRM series high-voltage probes are mainly used in high-frequency and high-voltage fields such as DC high-voltage power supplies X-ray power supplies electrostatic precipitator power supplies medical power supplies CT or PECT drive power supplies and various pulse high-voltage power supplies for measurement. The high-voltage probes can not only meet the requirements of harsh spatial electric field interference but also be used in a wide temperature environment.
