Product Details

Fluke 120B Series Industrial ScopeMeter 123B

Fluke 123B is the 20 MHz version of Fluke industrial ScopeMeter 120B Series. Each 120B model is an easy-to-use integrated test tool comprising oscilloscope, multimeter and high-speed recorder. It includes innovative functions designed to help troubleshoot faster and get the answers needed to keep systems up and running. Operators can display waveforms with Connect-and-View trigger and setup technology. They can view related numerical measurements using Fluke IntellaSet technology. These functions are free of the need to make manual measurement adjustments. With Recorder Event Detect capabilities, elusive intermittent events are captured and logged for easy viewing and analysis.
