Fluke 123B Industrial ScopeMeter Hand-Held Oscilloscope, 20 MHz

The Fluke 123B Industrial ScopeMeter® is designed for technicians who need a powerful, portable, and versatile troubleshooting tool for complex electrical systems. Offering 20 MHz bandwidth with dual-input capability, it provides simultaneous waveform and meter readings for fast, accurate diagnostics.

The Connect-and-View™ automatic triggering technology instantly recognizes signal patterns and sets the optimal trigger levels, ensuring a stable waveform display without manual adjustments—even for complex signals such as motor drives and control systems. Combined with IntellaSet™ technology, the oscilloscope intelligently analyzes the measured waveform and automatically displays the most relevant numerical readings, saving time and improving efficiency.

With built-in dual-input power measurement capabilities, the Fluke 123B calculates kW, VA, VAR, PF, and DPF for single-phase and balanced three-phase systems. The integrated recorder mode captures intermittent faults by logging both waveform and meter data, supporting event detection and long-term trending for up to 14 days.

The ScopeMeter includes Fluke Connect® compatibility, allowing technicians to view, save, and share results wirelessly using the Fluke Connect mobile app. With data stored securely in the Fluke Cloud, teams can collaborate remotely, compare historical measurements, and make informed decisions quickly.

Rugged and reliable, the Fluke 123B is IP51-rated and built to withstand 3 g vibration and 30 g shock, making it ideal for demanding industrial environments. It’s also CAT IV 600 V safety rated, ensuring maximum protection when troubleshooting high-energy systems.
