Fluke 190-104-III-S Handheld Oscilloscope

Overview

The Fluke 190-104-III-S is a portable 4-channel oscilloscope designed for field troubleshooting of complex electronic systems. With 100 MHz bandwidth and 1.25 GS/s real-time sampling, it captures detailed waveform information. The four fully isolated channels allow simultaneous measurements in circuits with different ground references, reducing the risk of accidental short circuits.

Built for harsh environments, the instrument carries a CAT III 1000 V/CAT IV 600 V safety rating and IP51 dust and drip-proof protection. A large color display provides clear visibility in the field. Data can be transferred to a PC via USB or optional WiFi for analysis with FlukeView software.
