Fluke FLUKE-190-204-III Portable Oscilloscope 200 Mhz 4ch

Product Description

The FLUKE FLUKE-190-204-III is a portable oscilloscope designed for field diagnostics and bench testing across industrial, electrical, and HVAC applications. It delivers a 200 MHz bandwidth across 4 independent channels, giving technicians the ability to capture and compare multiple waveforms simultaneously. Vertical deflection ranges from 2 mV/div to 100 mV/div, allowing precise measurement of both low-level signal anomalies and higher-amplitude waveforms. Licensed electricians, industrial maintenance techs, and advanced HVAC technicians reaching for a rugged, portable diagnostic tool will find this unit suited to demanding field environments.

This oscilloscope is built for portable use where bench-top instruments are not practical. It suits residential and commercial electrical troubleshooting, motor drive diagnostics, inverter and variable frequency drive analysis, and signal verification on control boards and low-voltage systems. The 4-channel configuration supports simultaneous monitoring of multiple circuit nodes, making it well suited to complex HVAC control wiring, building automation systems, and multi-phase electrical diagnostics.

Key Features

• 200 MHz bandwidth supports high-frequency waveform capture for inverter and VFD diagnostics
• 4 independent input channels allow simultaneous multi-signal comparison
• Vertical deflection range of 2 mV/div to 100 mV/div covers low-level and higher-amplitude signals
• LCD display provides clear waveform visualization in field conditions
• Portable form factor designed for use outside the shop or lab

Compatibility

Designed as a portable general-purpose oscilloscope suitable for use across electrical, HVAC, industrial maintenance, and instrumentation applications where waveform analysis is required.

Installation Notes

This oscilloscope is a test and measurement instrument, not a permanently installed component. Always de-energize or isolate the circuit under test before attaching probes where safe to do so, following NFPA 70E safe work practices. Use probe ratings appropriate for the voltage levels being measured. Electrical and instrumentation technicians should verify that input voltage levels do not exceed the rated input limits of the instrument before connecting to any live circuit.
