As the first two and four-channel portable scopes safety rated CAT III 1000V / CAT IV 600V, the new Fluke ScopeMeter®190 Series II combines an unprecedented level of performance, ruggedness, and portability. You can choose from 60MHz, 100MHz or 200MHz bandwidth models, both with real-time sampling rates up to 2.5 GS/s and 400 ps resolution to capture noise and other disturbances. Both models feature deep memory up to 10,000 samples per channe so you can examine very small parts of the waveform in detail. And both are IP-51 rated to withstand dust, drips, humidity, and wide temperature variations. Fluke ScopeMeter test tools are hand-held battery operated, designed to meet the demands of field service professionals.
