Fluke 190-204-III Handheld Oscilloscope

Overview

The Fluke 190-204-III is a portable 4-channel oscilloscope designed for comprehensive electrical testing of complex systems. With 200 MHz bandwidth and sampling rates up to 2.5 GS/s (2-channel mode) or 1.25 GS/s (4-channel mode), it delivers detailed waveform capture. The four fully isolated channels enable simultaneous measurements in circuits with different ground references.

Built for demanding field environments, the instrument carries a CAT III 1000 V/CAT IV 600 V safety rating and IP51 dust and drip-proof protection. The large color display ensures clear visibility, while dual USB ports and optional WiFi connectivity enable seamless data transfer to a PC for analysis with FlukeView software.
