Description
The Fluke 125B is a dual-input industrial ScopeMeter designed for comprehensive electromechanical troubleshooting. Combining a 40 MHz oscilloscope, a 5000-count digital multimeter, and a high-speed recorder in a single ruggedized chassis, this diagnostic tool is engineered for harsh field environments. It features Connect-and-View triggering for hands-off operation and IntellaSet technology to automatically adjust numerical readouts based on the measured signal. The inclusion of an AC current clamp expands its utility for direct power, energy, and harmonic measurements, making it a critical asset for plant maintenance.

Industrial Application
The Fluke 125B is specifically deployed in industrial automation environments for diagnosing variable frequency drives (VFDs), motor control centers, and power distribution networks. By utilizing the integrated BusHealth mode, technicians can verify the electrical signal quality of industrial buses (such as Profibus, Foundation Fieldbus, or Modbus) against established standards. The included AC clamp allows for immediate power quality analysis, identifying harmonic distortion, voltage sags, and transient anomalies that cause intermittent machine failures and logic controller resets.
Procurement and Lifecycle Value
Sourced through Original Engineering channels, the Fluke 125B ensures exact Technical Compatibility with existing Fluke diagnostic software architectures, including FlukeView for Windows. Standard Lead Time applies for this factory-calibrated instrument, guaranteeing immediate deployment readiness for critical plant maintenance and minimizing costly production downtime.
