The NRV series high-voltage probes are used in the field of high-frequency and high-voltage measurement, 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. The high-voltage probes can not only meet harsh spatial electric field interference, but also be used in wide temperature environments.
Overview
Product Introduction
The NRV series high voltage probes are used in the field of high-frequency and high-voltage measurement 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. The high-voltage probes can not only meet harsh spatial electric field interference but also be used in wide temperature environments.
Product Characteristics
1. Standard BNC interface that can be connected to an oscilloscope.
2. The NRV series high voltage probe adopts imported low temperature coefficient resistors and capacitors.
3. The NRV series high voltage probes adopt symmetrical full shielding measures to reduce proximity effects (stray capacitance) while ensuring consistency and stability in testing.
4. The NRV series high voltage probes have been calibrated for both high and low frequencies ensuring accurate measurements in each frequency band.
5. The NRV series high voltage probes undergo special compensation and do not require additional calibration when using oscilloscopes from different manufacturers.
