Fluke FLUKE-190-104-III Portable Oscilloscope 100 Mhz 4ch

Product Description

The FLUKE FLUKE-190-104-III is a portable, four-channel oscilloscope built for field and bench diagnostics by electricians, HVAC technicians, and instrumentation professionals. It delivers a 100 MHz bandwidth across all four input channels simultaneously, with a vertical deflection range of 2 to 100 millivolts per division. The LCD display provides clear waveform visualization in a compact, handheld form factor. At 4.8 pounds, the unit is designed to travel to job sites, equipment rooms, and service panels without sacrificing measurement capability.

This oscilloscope is suited for residential and light commercial electrical troubleshooting, motor drive diagnostics, variable-frequency drive output analysis, and control circuit verification. Technicians use four-channel units when they need to compare signals across multiple phases or control lines simultaneously. The portable format makes it practical for service calls where benchtop equipment is not an option.

Key Features

• 100 MHz bandwidth supports accurate capture of fast transient signals
• Four independent input channels for simultaneous multi-signal comparison
• Vertical deflection range of 2 to 100 mV/div for fine and coarse signal resolution
• LCD display for clear waveform reading in varied lighting conditions
• Portable handheld design at 4.8 pounds for field service use

Compatibility

Designed as a portable handheld oscilloscope for general electrical and electronic diagnostics across industrial, commercial, and residential service applications.

Installation Notes

Installation and use of this oscilloscope should be performed by qualified electricians or instrumentation technicians familiar with voltage measurement safety practices. Always verify that input voltage levels do not exceed the rated category and voltage specifications printed on the unit before connecting probes. De-energize circuits where safe and practical before attaching test leads. Follow applicable NEC and site safety requirements when working in electrical panels or near live conductors.
