Fluke 190-104-III, Portable Digital Storage Oscilloscope, 100MHz, 4 Channels

The Fluke 190-104-III is a rugged, portable digital storage oscilloscope designed for technicians who need high-resolution waveform analysis in industrial environments. With a 100 MHz bandwidth and four independent channels, it allows users to capture, compare and diagnose complex electrical signals in power electronics, automation systems and control circuits. Built to withstand harsh field conditions, the instrument offers CAT III 1000 V / CAT IV 600 V safety ratings, making it suitable for demanding troubleshooting work.

Crucial Features and Benefits of Choosing the Fluke 4-Channel Portable Digital Storage Oscilloscope

• 100 MHz of analogue bandwidth for capturing fast, transient, or high-frequency signals.
• 4 fully isolated input channels for safe measurement of mixed-voltage systems.
• High sampling rate and deep memory for detailed waveform capture.
• Portable design with battery operation for on-site diagnostics.
• Configurable triggering tools to isolate intermittent events or irregular signal behaviour.
• Built-in DMM functions supporting additional electrical measurements when needed.

Practical and Useful for Technical Work

The 190-104-III enables field engineers to study power quality issues, switching behaviour, and control-system signals without bench-top equipment. Its isolated inputs help prevent ground-loop errors when measuring systems with different reference points. The display layout supports clear waveform comparison, while the robust housing resists dust, shocks and environmental stress typically encountered during plant and facility work.

Applications Across Various Industries

• This oscilloscope is commonly used for diagnosing motor-drive outputs, inverter switching patterns, automation-system timing signals and irregular behaviours in power electronics.
• It is valuable in commissioning, maintenance and fault-finding tasks where transient events and intermittent faults must be captured accurately.
• Whether used in manufacturing plants, energy systems or service environments, the Fluke 190-104-III provides reliable, high-resolution waveform insight for complex electrical systems.
