Portable Oscilloscopes Suit Harsh Industrial Environments

Fluke Corporation has introduced the ScopeMeter 190 Series II handheld portable oscilloscopes, said to be the first four-channel scopes that are safety rated for CAT III 1000 V/CAT IV 600 V environments. The four input channels are fully isolated from each other to perform differential floating measurements, a consideration for troubleshooting fixed-installation three-phase power electronic devices like variable speed motor drives. The Fluke ScopeMeter chassis is sealed from the environment with no cooling slots or fans to expose the instrument. It carries the International Protection (IP) -51 dust and drip proof rating so it’s tough enough to use—safely—on the factory floor and in the field. Their sampling rate, up to 2.5 GS/sec and 400 ps resolution, helps users capture electrical noise and other disturbances to diagnose exactly what is going on. The scopes are offered in 100 MHz and 200 MHz models.
