Fluke 125B Industrial ScopeMeter Hand-Held Oscilloscope with AC clamp, 40 MHz

The Fluke 125B ScopeMeter® is engineered for technicians and engineers who work on complex industrial systems, drives, and networks. With a dual-input, 40 MHz bandwidth oscilloscope and integrated true-RMS digital multimeter, it provides fast, reliable insights into electrical and power quality issues.

Its unique Connect-and-View™ triggering automatically locks onto signals — from motor drives to control circuits — without manual adjustments, ensuring stable waveforms every time. The IntellaSet™ function goes a step further by automatically analyzing signals and displaying the most relevant numerical values, speeding up troubleshooting and reducing guesswork.

With BusHealth tests, the 125B can quickly evaluate the physical layer quality of common industrial networks (CAN, Profibus, RS-232, RS-485, etc.), giving clear “Good/Weak/Bad” indicators to pinpoint wiring or grounding issues. For long-term monitoring, it features advanced recorder modes, capturing intermittent faults with event detection and recording sessions of up to 14 days using its internal memory or microSD card.

Designed for field use, the IP51-rated housing, CAT IV 600 V safety rating, and resistance to shock (30 g) and vibration (3 g) make it a trusted companion in demanding industrial environments. Wireless connectivity through the Fluke Connect® app allows teams to view, store, and share measurements remotely, improving efficiency and collaboration.

Features

• Dual-input oscilloscope and multimeter — Combines 40 MHz bandwidth scope with two independent 5000-count true-RMS meters.
• Connect-and-View™ auto-triggering — Instantly provides stable waveforms without manual adjustments, even on motor drives and complex signals.
• IntellaSet™ technology — Automatically selects and displays the most relevant numerical readings (e.g., Vrms + Hz for AC, Vpp + Hz for square waves).
• Power and harmonic analysis — Measures W, VA, var, PF, DPF, Hz, and voltage/current harmonics for single-phase and balanced 3-phase systems.
• Recorder with event detect — Captures elusive intermittent faults with threshold tagging and recording for up to 14 days.
• Industrial BusHealth testing — Validates physical layer signal quality of CAN, Profibus, Foundation Fieldbus, RS-232, RS-485, and more.
• Integrated digital multimeter functions — Resistance, continuity, diode, capacitance, frequency, duty cycle, and temperature measurements.
• Rugged IP51 design — Withstands 30 g shock, 3 g vibration, and built for harsh industrial conditions.
• Fluke Connect® compatibility — Wirelessly share data, store results, and analyze trends via mobile app and cloud storage.
• Long battery life — Rechargeable Li-ion battery provides up to 7 hours of operation per charge.
