Fluke 190-204-III, Portable Digital Storage Oscilloscope, 200MHz, 4 Channel

The Fluke 190-204-III is a rugged, industrial-grade portable digital storage oscilloscope engineered for on-site commissioning, service, and troubleshooting of automation systems, power conversion electronics and manufacturing equipment. With a 200 MHz bandwidth and four isolated floating channels, it offers high-fidelity waveform capture and analysis in demanding environments. The instrument incorporates deep memory, versatile triggering modes and multi-interface connectivity, making it ideal for maintenance engineers and field service professionals.

Crucial Features and Benefits of Buying the Fluke Portable Digital Storage Oscilloscope

• 4 fully isolated input channels enable simultaneous multi-point measurements with up to 1000 V float between inputs.
• 200 MHz bandwidth, paired with up to 5 GS/s real-time sampling (model-dependent), ensures accurate capture of high-speed events.
• Industry-rated safety: CAT III 1000 V / CAT IV 600 V suitability for harsh industrial and electrical-distribution environments.
• Deep memory and recorder functions (e.g., up to 10,000 samples per channel in scope mode, and long-duration recording via ScopeRecord™/TrendPlot™) support detailed post-analysis of transient and drift events.
• Rugged, portable construction with IP51-rated housing, shock-tested for field durability, and full-colour display for visibility in less-than-ideal lighting.

What Sets this Oscilloscope Apart?

The 190-204-III is built to deliver dependable waveform capture and analysis in challenging industrial settings where downtime, faulty drives and complex signals are critical. The robust design ensures reliability under harsh conditions while the field-friendly interface and instrumentation features reduce set-up time, enabling technicians to focus on fault resolution rather than instrument configuration.
