Product Description

1. Product Introduction
NRM series high voltage probe is 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 newly developed high-voltage probe, not only can it 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 top 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, Tsinghua University, North China Electric Power University, Wuhan University of Technology, Southwest Institute of Physics for Nuclear Industry and other units..

3. Product characteristics
1) Standard BNC interface, compatible with all manufacturers of oscilloscopes;
2) Configure special interface to connect the oscilloscope or multimeter to measure;
3) NRV series high voltage probe adopts the low temperature coefficient resistors imported from America and capacitors which is extremely stable for temperature, frequency and voltage;
4) NRV series high voltage probe using fully symmetrical shielding measures to reduce the proximity effect (stray capacitance) and maximally guarantee the consistency and stability of the test;
5) The high and low frequency of NRV series high voltage probe had been calibrated strictly, even the coaxial cable for high frequency is also compensated by frequency, so that to ensure each frequency band can realize accurate measurement;
6) NRV series high voltage probe trough special compensation, it does not need additional calibration when using different manufactures of oscilloscope.
