With a 40 MHz bandwidth, dual analogue inputs, automatic waveform capture (Connect-and-View™), built-in power/harmonic...

The Fluke 124B is a rugged handheld industrial ScopeMeter® instrument combining a dual-input oscilloscope, true-RMS multimeter and recorder in one tool. With a 40 MHz bandwidth, dual analogue channels, Connect-and-View™ automatic triggering and dedicated “cursor” read-out capability for waveform analysis and measurement, it handles...

The Fluke BT520ANG Advanced Battery Analyzer is a rugged, high-feature handheld instrument designed for professional maintenance and diagnostic tasks in large stationary battery systems. It offers comprehensive measurement capabilities—such as internal battery resistance, DC voltage and current, AC ripple detection and temperature logging—all in...

The Fluke 1664 FC is a professional-grade multifunction installation tester designed for electrical contractors and service engineers working in domestic, commercial and light industrial environments. It supports all key installation tests—insulation resistance at 50/100/250/500/1000 V, loop and line impedance with mΩ resolution, continuity at...

Incorrect phase sequence can cause motors and other three-phase equipment to rotate in the wrong direction, creating commissioning delays or mechanical problems. The Fluke 9040 Phase Rotation Indicator provides a straightforward way to confirm the presence of three phases and their rotational sequence before...

Industrial electricians often need a quick electrical tester that covers higher-voltage installations without the complexity of a full multimeter. The Fluke T5-1000 Voltage, Continuity and Current Tester combines voltage, resistance, continuity and OpenJaw current measurement in a compact format. The tester measures AC/DC voltage...

Routine electrical troubleshooting often requires only three answers: is voltage present, how much current is flowing and is the circuit continuous? The Fluke T5-600 Electrical Tester combines these functions in a compact instrument designed for quick front-line diagnostics. Its OpenJaw design measures AC current...

Motor and equipment troubleshooting is faster when you can view voltage and current together rather than measure them separately. The Fluke T6-1000 PRO Electrical Tester combines FieldSense technology with simultaneous voltage and current display, letting technicians see key supply conditions through the open fork...

Connecting test probes to exposed conductors can slow routine troubleshooting, particularly inside crowded electrical cabinets. The Fluke T6-600 Electrical Tester uses FieldSense technology to measure True-RMS AC voltage, current and frequency through an open fork without requiring test-lead contact to the live conductor. FieldSense...

For straightforward electrical service, technicians often need fast confirmation of voltage and continuity rather than the broader functions of a digital multimeter. The Fluke T+ Electrical Tester provides a rugged solution using light, sound and vibration to indicate AC/DC voltage, allowing the technician to...

Electrical troubleshooting can become difficult in dark, noisy or restricted locations when a technician depends on only one indication method. The Fluke T+PRO Electrical Tester provides light, sound and vibration indications for AC/DC voltage so the presence of voltage can be recognized under varied...

The Fluke BT521ANG Advanced Battery Analyzer with angled test probes is a high-precision instrument designed for testing and monitoring stationary battery systems and battery banks. It delivers measurements of internal battery resistance (down to milliohms), DC and AC voltage, AC and DC, ripple voltage,...

Battery testing inside densely packed racks and cabinets becomes inefficient when the technician must repeatedly move between the battery terminals and the analyzer display. The Fluke BT520 Battery Analyzer addresses this problem with the BTL20 intelligent test probe set, designed specifically for battery cabinets...

A battery bank can still show acceptable terminal voltage even when individual cells begin to deteriorate, so voltage measurement alone is insufficient for preventive maintenance. The Fluke BT510 Basic Battery Analyzer is designed for systematic testing of stationary batteries used in UPS systems, telecom...

The Fluke 1663 Multifunction Installation Tester is a professional-grade tester built for verifying fixed wiring installations in domestic, commercial and industrial settings. It performs insulation resistance testing at multiple voltages (50 V to 1000 V), loop and line impedance (down to milliohm resolution), continuity...

The Fluke 123B Industrial ScopeMeter is a premium dual-input handheld instrument combining an oscilloscope, true-RMS multimeter and recorder—all in one rugged unit. With a 20 MHz bandwidth oscilloscope, two 5000-count true-RMS digital multimeters, Connect-and-View™ automatic triggering and IntellaSet™ auto-measurement technology, it enables industrial technicians to quickly...
