Fluke 123BS Portable Industrial Oscilloscopes (20 MHz)
The Fluke 123B/S Industrial ScopeMeter is a compact, rugged handheld oscilloscope tailored for industrial electrical and electro-mechanical equipment troubleshooting and maintenance. It combines the functionalities of a dual-input digital oscilloscope and multimeter, offering a 20 MHz oscilloscope bandwidth. This instrument is designed to facilitate faster troubleshooting, thanks to features like Connect-and-Viewâ„¢ triggering and IntellaSetâ„¢ technology.
The former automatically displays stable waveforms without manual adjustment of amplitude, timebase, and trigger settings, while the latter analyzes the signal and automatically displays relevant numerical readings, making data interpretation more straightforward.
The Fluke 123B/S also features a dual-input waveform and meter reading recorder for extended data trending, along with a Recorder Event Detect function that captures elusive intermittent signals, enhancing its utility for complex industrial applications. It’s designed to withstand harsh environments, evidenced by its ability to endure 3g vibration, 30g shock, and its IP51 rating for dust and drip protection. It boasts the highest safety rating in the industry, CAT IV 600 V.
For more detailed specifications and applications, the Fluke 123B/S supports measurements like resistance, diode, continuity, capacitance, and power measurements, and it’s equipped with shielded test leads for various measurements. Its compatibility with the Fluke Connect mobile app enhances its utility by allowing for easy data sharing and analysis. The ScopeMeter is ideal for maintenance applications, where understanding signal characteristics and changes over time is crucial, and it can also assist in pinpointing intermittent faults efficiently​.
