The Fluke 190-104-III-S is a four-channel, 100 MHz handheld color oscilloscope built for industrial field service and troubleshooting. It combines waveform capture with integrated 5000-count digital multimetry, delivering real-time analysis and long-term data logging via USB and optional Wi-Fi connectivity. The instrument isolates all measurement inputs, making it safe for mixed-ground circuits and systems rated to CAT III 1000 V / CAT IV 600 V.
