The Fluke 125B Industrial ScopeMeter is a hand-held, dual-channel oscilloscope that combines waveform capture, digital multimetry, and data recording into a single rugged instrument for industrial electrical and electro-mechanical troubleshooting. Operating at 40 MHz bandwidth with 40 MS/s sample rate, it delivers real-time signal analysis alongside true-RMS power measurements, network diagnostics, and wireless data connectivity. Connect-and-View™ triggering eliminates manual setup by automatically stabilizing waveforms, while IntellaSet™ technology extracts critical numerical parameters without user intervention. Built-in BusHealth physical layer testing supports industrial protocols including CANbus, Profibus, Foundation Field Bus, and RS-232. An integrated AC current clamp enables non-invasive current measurement. The instrument meets CAT IV 600 V / CAT III 750 V safety ratings and integrates with Fluke Connect mobile app via optional WiFi for remote data access and archival.
