Simplified testing, more insight and faster

electro-mechanical troubleshooting

The compact ScopeMeter

120B Series, is the rugged oscilloscope

solution for industrial electrical and electro-mechanical equip-

ment troubleshooting and maintenance applications. It’s a truly

integrated test tool, with oscilloscope, multimeter and high-speed

recorder in one easy-to-use instrument. The ScopeMeter 120B

Series also integrates with Fluke Connect

mobile app and

FlukeView

for ScopeMeter software to enable further collabora-

tion, data analysis and archiving of critical test information.

The 120B Series Industrial ScopeMeter Test Tools include innova-

tive functions designed to help technicians troubleshoot faster and

get the answers they need to keep their systems up and running.

Display waveforms with Connect and View™ trigger and setup

technology and automatically view related numerical measure-

ments using Fluke IntellaSet™ technology, all without making

manual measurement adjustments. With Recorder Event Detect

capabilities, elusive intermittent events are captured and logged

for easy viewing and analysis.

• Dual-input digital oscilloscope and multimeter

• 40 MHz or 20 MHz oscilloscope bandwidth

• Two 5,000-count true-rms digital multimeters

• Connect-and-View™ trigger simplicity for hands-off operation

• IntellaSet™ technology automatically and intelligently adjusts

numerical readout based on the measured signal

• Dual-input waveform and meter reading recorder for

trending data over extended periods

• Recorder Event Detect captures elusive intermittent signals on

repetitive waveforms up to 10 KHz

Industrial equipment needs a reliable power supply to operate properly, use the dual input to obtain key power measurements. For single phase or 3-phase balanced systems, the dual inputs of the Industrial ScopeMeter® 120B Series can measure ac+dc rms voltage on channel A and ac+dc rms current on channel B.
