Fluke 125B/S Industrial ScopeMeter Hand-Held Oscilloscope with AC clamp and Fluke View software, 40 MHz

The Fluke 125B/S Industrial ScopeMeter® is engineered for professionals who maintain and troubleshoot industrial electrical, electro-mechanical, and power systems. With its 40 MHz bandwidth, dual-input measurement capability, and integrated true-RMS digital multimeter, this portable oscilloscope provides accurate waveform analysis, power diagnostics, and fault detection in a single tool.

Its Connect-and-View™ triggering technology automatically identifies signal patterns and instantly locks onto stable waveforms without manual adjustments. Combined with IntellaSet™ intelligent auto-readings, it displays the most relevant measurement data, making troubleshooting faster and easier. Whether analyzing voltage, current, harmonics, resistance, capacitance, or power factor, the ScopeMeter delivers reliable insights for technicians working on drives, control systems, and industrial networks.

The dual-channel input allows simultaneous measurement of voltage and current, enabling calculations of active power (kW), reactive power (VAR), apparent power (VA), frequency, phase angle, and power factor for both single-phase and balanced three-phase systems. The integrated harmonics analysis function measures up to the 51st harmonic, providing detailed insights into power quality issues caused by non-linear loads such as drives, power supplies, and motor controllers.

Equipped with advanced Recorder Event Detect, the 125B/S captures elusive intermittent faults by automatically tagging anomalies for easy review. Combined with expandable microSD storage, it supports waveform and meter recordings for up to 14 days, making it ideal for long-term monitoring and preventive maintenance.

For industrial network diagnostics, the built-in BusHealth testing feature evaluates the physical layer quality of protocols like CAN, Profibus, Foundation Fieldbus, RS-232, RS-485, and Modbus, indicating signal integrity with simple Good/Weak/Bad status reports.

Integration with Fluke Connect® mobile app and FlukeView® PC software allows seamless data transfer, remote monitoring, trend analysis, and report generation. Its CAT IV 600 V safety rating, IP51 ingress protection, and rugged shock-resistant design make it highly durable for field operations.
