Fluke 40 MHz Bandwidth 2 Channel Digital Handheld Oscilloscope 5.7 in TFT Colour Display FLUKE-125B/UK/S

Fluke FLUKE-125B/UK/S is a 40 MHz bandwidth handheld digital oscilloscope with two channels and a 5.7 inch TFT colour display. Designed for industrial electrical and electromechanical troubleshooting, this portable instrument combines waveform capture, dual-input metering, and recorder features. It captures voltage, current, and power characteristics on-site and interfaces safely with PCs and mobile devices through an optically isolated USB link or an optional wireless adaptor.

This oscilloscope provides precise measurements with an 8.75 ns rise time and a minimum vertical sensitivity of 5 mV/div, allowing detailed observation of low-amplitude signals. Its maximum vertical sensitivity is 200 V/div, supporting high-voltage industrial testing. The device is battery operated using a rechargeable lithium-ion battery that offers approximately 7 hours of runtime, suitable for field operation.

Applications include commissioning motor drives and inverter outputs, power quality measurement through active, reactive, and apparent power calculation, harmonics analysis up to the 51st order, and diagnosing intermittent faults using event-tagged recording to internal or SD card memory. It also supports industrial bus physical-layer signal assessment and routine electromechanical maintenance.

The FLUKE-125B/UK/S meets various safety standards, including CSA, EMC, and WEEE, and complies with CAT III and CAT IV safety category ratings at 750 V, making it suitable for rigorous industrial environments. Its robust design withstands vibration, shock, and meets IP51 ingress protection standards.

Dimensions are compact at 55 mm height, 55 mm width, and 132 mm depth, facilitating easy handling onsite. The unit is manufactured in Romania, ensuring high build quality and reliability.
