Fluke ScopeMeter 125B/EU/s handheld-oscilloscoop 40 MHz 2-kanaals 4 GSa/s (4756054)

The Fluke ScopeMeter 125B/EU/s combines a 40 MHz dual-channel oscilloscope with a full digital multimeter in one rugged, handheld unit. Unlike benchtop scopes that tie you to the lab, this ScopeMeter is built for field service, plant maintenance, and troubleshooting on the move. Its Connect-and-View™ trigger automatically sets up stable waveforms, while the 5.7-inch colour LCD shows clear readings even in bright or dim conditions. With CAT III 1000V and CAT IV 600V safety ratings, it is safe for industrial power distribution work.

Highlights

• 40 MHz bandwidth, 2 isolated channels, 4 GSa/s equivalent-time sampling
• Integrated 5000-count DMM with VDC, VAC, ADC, AAC, resistance, continuity, diode, and capacitance
• TrendPlot™ paperless recording for long-term signal monitoring
• Rechargeable Li-ion battery provides up to 7 hours of portable operation
• USB connectivity for PC data transfer and remote control

In daily use

The ScopeMeter 125B/EU/s is a true all-in-one troubleshooting tool. The scope section offers 5 mV/div to 100 V/div vertical sensitivity and a time base from 10 ns/div to 2 min/div, capturing fast transients or slow drift. Automatic measurements include Vpeak, Vrms, frequency, period, duty cycle, pulse width, and rise/fall time. The multimeter function reads true RMS AC/DC voltage and current, plus resistance, continuity, diode, and capacitance. TrendPlot™ lets you record up to 22 days of data for intermittent fault hunting. The IP51 rating protects against dust and dripping water, and the rugged case withstands drops and rough handling.
