✅ Key Features of the FLUKE T150 Voltage Tester
1. Comprehensive Voltage Measurement
Measure both AC and DC voltages from 6 V up to 690 V. Perfect for residential, commercial, and industrial use.
2. Dual Display System
The FLUKE T150 features a backlit LCD and high-visibility LED bar indicators. This combined system delivers both digital accuracy and fast visual confirmation. Includes a display hold function, allowing you to freeze readings for convenient viewing in tight or awkward spaces.
3. Continuity and Resistance Testing
Detects circuit continuity with visual and audible alerts up to 400 kΩ. Also operates as a voltage continuity tester, displaying resistance values from 1 Ω to 1,999 Ω — ideal for diagnosing corroded joints or partially severed cables.
4. Phase Rotation Indication
Quickly identify the phase sequence between 100 and 690 V AC — a must for safe three-phase installation and maintenance.
5. Load Function with RCD Trip Capability
Eliminate ghost voltages by applying a genuine load to the circuit. Engage RCDs up to 30 mA to validate disconnection systems.
6. Integrated Torchlight
An ultra-bright white LED torch makes inspecting dark panels or recesses safe and hassle-free.
7. Vibration Feedback
Confirms voltage presence under load through vibration — ideal in noisy environments where audible alerts may be missed.
8. Smart Cable Safety
Built-in CableHealth alerts you to damaged leads before use. FLUKE’s exclusive WearGuard™ system shows insulation wear through a two-layer cable design for early replacement.
