Product introduction

NRV Series ultra high-voltage probes is the latest product which is researched and developed by our company, we have invested heavily and took more than 3 years, combined with some of the top universities and laboratories to research and develop the new product. we have complete independent intellectual property rights.

NRV Series ultra high-voltage probes can be used for various of high voltage measurement, it can meet various measuring requirements of high frequency and high voltage, high voltage switch, military equipment and so on. NRV Series ultra high-voltage probes is adopt special low temperature coefficient resistors and capacitors as the main components, joining our company's patented internal shielding technology, so that the high-voltage probes has an excellent high-frequency characteristics and high measurement stability.

NRV Series ultra high-voltage probes are widely used in the manufacturing and operating of TV radar tube and the particle accelerator. We will calibrate high and low frequency before delivery, and also compensate and match the high frequency cable to ensure the stability and high repetition of the high frequency divider. The operating mode is the same as low voltage probes, it is equipped with an oscilloscope interface.

Alternative name

HV probes, High voltage probe

The Characteristics of the products

1.Standard BNC interface, compatible with all manufacturers of oscilloscopes.

2.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.

3.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.

4.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 measurements.

5.NRV series high voltage probe trough special compensation, it do not need additional calibration when using different manufactures of oscilloscope.

D-is DC, used for measuring DC voltage;
A-is AC, used to measuring AC voltage;
HF-is high and the frequency of the first letters used to measure high frequency voltage
P- is pulse, used for measuring the pulse voltage.

Ordering Information:
FRC series voltage divided into three kinds products based on different types of measurements
1, FRC capacitive divider (FRC said measuring AC also called AC voltage divider);
2, FRC RC divider (or called FRC AC and DC voltage divider that can measure AC and DC);
3, FRC resistor divider (or called FRC DC voltage divider for measuring DC)
If do not indicate the type, it defaults to AC and DC voltage divider
