Fluke 190-204-III CAL ScopeMeter

Overview

The Fluke 190-204-III CAL ScopeMeter is a factory-calibrated, professional-grade portable oscilloscope engineered for demanding industrial field service, maintenance, and regulated environments requiring traceable measurement documentation. This four-channel model delivers the measurement capability of a bench oscilloscope in a rugged, battery-powered form factor, with a full calibration certificate providing assurance of measurement accuracy. Designed for plant maintenance engineers and technicians, it excels in harsh, dirty, and hazardous industrial environments, enabling precise troubleshooting of complex industrial systems, three-phase power electronics, and multi-channel control circuits.

The 190-204-III CAL features four fully isolated input channels, each independently selectable for maximum measurement flexibility in mixed-voltage environments. Its 200 MHz bandwidth, 1.7 ns rise time, and 1.25 GS/s simultaneous sampling across all four channels provide the detailed waveform capture and analysis capability required for complex diagnostics. Advanced recording modes (TrendPlot, ScopeRecord) enable continuous monitoring and detection of intermittent faults. The CAT IV 600V/CAT III 1000V safety rating ensures safe operation in high-voltage systems.
