Fluke 190-104 ScopeMeter® Test Tool

The Fluke 190-104 ScopeMeter® brings four-channel testing power to industrial troubleshooting with unmatched safety and portability. Designed for demanding applications, it features 1.25 GS/s sampling speed and 100 MHz bandwidth to capture fast-changing signals, harmonics, and transient events with precision.

Its four fully isolated inputs rated up to CAT III 1000V / CAT IV 600V allow simultaneous measurements across multiple circuits without worrying about ground loops or accidental shorts, making it ideal for three-phase systems, VSD testing, and mixed-signal diagnostics.

With ScopeRecord™, you can capture up to 30,000 data points per channel for deep waveform analysis, while TrendPlot™ continuously records up to 22 days of measurement data to identify intermittent faults. The Connect-and-View™ auto-triggering function automatically adjusts to signal patterns for a stable display without manual configuration, allowing faster, hands-free troubleshooting.

Equipped with a built-in 5000-count digital multimeter, the 190-104 supports voltage, resistance, continuity, diode test, current, and temperature measurements — making it a versatile all-in-one test solution. Rugged and IP51-rated, it withstands dust, drips, humidity, and harsh field conditions.

Its dual isolated USB ports make data transfer seamless, allowing easy waveform storage and PC integration using FlukeView® software. Powered by the high-capacity BP291 Li-ion battery, it delivers up to 7 hours of continuous operation on a single charge, ensuring uninterrupted productivity during long field sessions.
