The Fluke 125B/S Industrial ScopeMeter is a 40 MHz dual-channel handheld oscilloscope that combines oscilloscope, multimeter, and paperless recorder functionality into one rugged platform for troubleshooting industrial electrical and electromechanical equipment. Connect-and-View™ Triggering automatically stabilizes waveform display regardless of signal variation, while IntellaSet™ Technology intelligently analyzes measured signals and automatically populates relevant numerical measurements. The instrument captures intermittent faults on repetitive waveforms up to 4 kHz and verifies industrial network signal quality via BusHealth testing.
