Ponta de prova de alta tensão Fluke 80K-40 40 kV DC/pico AC, 1000:1, preto/vermelho 382846

Measuring high voltages safely requires a probe that can handle extreme potential without compromising accuracy. The Fluke 80K-40 high voltage probe extends the measurement capability of your digital multimeter to 40 kV DC or peak AC, converting high voltage into a low-level signal your meter can read directly.

Who is it for

This probe is essential for technicians and engineers working with high-voltage equipment such as CRT displays, power supplies, X-ray systems, and electrostatic precipitators. It is compatible with multimeters that have a 10 MΩ input impedance, providing a 1000:1 attenuation ratio for accurate readings.

Main features

• Measures up to 40 kV DC or peak AC
• 1000:1 attenuation ratio for safe, accurate readings
• High input impedance of 100 MΩ when used with a 10 MΩ meter
• Shrouded banana plugs for secure connection
• 1 meter cable length for flexibility
• Black and red colour scheme for high visibility

Tips

Always verify that your multimeter has a 10 MΩ input impedance before use. For AC measurements above 1 kHz, accuracy may degrade; consult the manual for derating curves. Ensure the probe is properly grounded and keep the cable away from high-energy circuits to avoid interference.
