125B-INDUSTRIAL-BAG

The Fluke 125B is the top model of Fluke's 120B Series Industrial ScopeMeter line: a battery-powered handheld instrument that combines a two-input 40 MHz digital oscilloscope, two true-rms multimeters and a recorder. It is aimed at electrical and electro-mechanical troubleshooting in industrial plants.

Fluke's Connect-and-View triggering sets up a stable display without manual adjustment, and IntellaSet picks the numeric readings that suit the measured signal. Compared with the 123B and 124B, the 125B adds power measurements (W, VA, var, PF, DPF), harmonics up to the 51st, and a Bus Health test that grades the electrical signal quality of field buses such as CAN, Profibus, Modbus, AS-i and Foundation Fieldbus as good, weak or bad.

The instrument is rated CAT IV 600 V / CAT III 750 V, has a 640 x 480 colour screen, a Li-ion battery for about seven hours of use and a micro SD slot for long recordings. Data goes to a PC through the optically isolated OC4USB cable and FlukeView ScopeMeter software, or wirelessly with the optional WiFi adapter and the Fluke Connect app.

Fluke's standard 125B kit includes the i400s AC current clamp and a 10:1 voltage probe; the 125B/S kit adds a soft carrying case, FlukeView software, a magnetic hanger and a screen protector.
