The Fluke 190 Series III is an industrial-grade portable 2-in-1 ScopeMeter integrating high-performance oscilloscope and digital multimeter functions, engineered for fault diagnosis of industrial automation, power electronics, new energy vehicles, servo drives and on-site equipment. The series offers 2-channel and 4-channel models with bandwidth ranging from 60 MHz to 500 MHz, equipped with independent floating isolated input channels and industry-leading safety rating CAT III 1000 V / CAT IV 600 V, enabling safe direct measurement on high-voltage incoming cabinets, inverters and other harsh high-voltage environments.

Adopting patented Connect-and-View™ auto triggering technology, the unit automatically captures stable complex dynamic waveforms without manual adjustment of time base, amplitude or trigger settings. It comes with built-in TrendPlot paperless recorder, ScopeRecord long-duration roll recording and 100-screen waveform replay functions, paired with a 5-inch high-bright color touch LCD for clear visibility under direct outdoor sunlight. Wi-Fi and USB data export are supported, with one-click standardized test report generation via FlukeView professional analysis software for in-depth waveform analysis. It serves as the core handheld measuring instrument for on-site maintenance, production line commissioning and laboratory R&D.
