Description
P9000 Differential Probe for Safe High Voltage Measurement
The P9000 Differential Probe is engineered to provide accurate and safe high-voltage signal measurements when paired with Hioki Memory HiCorders. Designed for demanding CAT III environments, this probe supports up to 1000 V AC or DC, making it suitable for industrial, automotive, and energy-related applications.
Built with user safety and measurement precision in mind, the P9000 allows engineers and technicians to observe instantaneous waveforms or RMS values without compromising signal integrity. Its DC to 100 kHz bandwidth ensures reliable waveform capture, while the RMS mode on the P9000-02 enables accurate voltage trend analysis in dynamic systems.
The probe’s selectable division ratios of 1000:1 and 100:1 provide flexibility across a wide range of voltage levels. With low input capacitance and high input resistance, it minimizes circuit loading, allowing precise measurements even in sensitive high-voltage circuits.
Thanks to its compact housing and lightweight design, the P9000 Differential Probe is easy to deploy in confined spaces such as electric vehicle battery compartments or inverter enclosures. It connects directly to a Memory HiCorder’s analog input terminal and can be powered through an AC adapter, USB bus power, or an external DC supply, offering versatile setup options.
The probe is widely used for analyzing high-voltage battery circuits in EVs and HEVs, photovoltaic power systems, commercial power lines, and surge noise generated by motors, inverters, and solenoids. With a wide operating temperature range and a one-year accuracy guarantee, the P9000 delivers dependable performance in both field and laboratory environments.
Whether you are troubleshooting power electronics, validating energy systems, or monitoring industrial equipment, the P9000 Differential Probe provides the safety, accuracy, and flexibility required for professional high-voltage testing.
