The Fluke 1555 insulation resistance tester offers digital insulation testing up to 10 kV, making it ideal for testing high voltage equipment including switchgear, motors, generators and cables.
Data collection is easy using the Fluke Connect® wireless app. Remote operation lets you spend as little time as possible in potentially hazardous zones. Real-time trending shows a live graph on your phone, rather than a hard-to-read set of changing values. And you can create reports quickly, using pre-designed templates that you can customize with company logos. The 1555 insulation tester can now conduct the entire range of test voltages specified in IEEE 43-2000 with a best in class, 3 year warranty and CAT IV 600 V safety rating.

How do we test our new and improved Two-Pole Voltage and Continuity Testers?

Two-pole voltage and continuity testers measure voltage, but just as important is when a two-pole tester tells you that there is NOT voltage present before working on any circuit. For you to rely on your two-pole tester, it has to be the most rugged and reliable tester you can find. That’s what Fluke’s redesigned two-pole testers give you.
Fluke knows the cable assembly is often where failures occur. The cable on any Two-Pole voltage and continuity tester is its weakest point- it is repeatedly bent, twisted, wrapped and put under constant strain. If the cable were to break, it could place you at an increased safety risk. Industry standards call for the cable to be tested to withstand a forty-five-degree bend, and still work after 5000 bend cycles. Fluke puts our testers through three times what the standard demands, flexing the cable over 150 degrees in each direction. This is why we can offer you our strongest voltage and continuity testers warranty ever.
Other useful features
• Dual insulated cable tested to 3x the required bend angle provides increased reliability and durability.
• Switchable load: avoid display of ghost voltages allowing you to draw more current from the circuit under test and avoid trip residual-current devices (RCDs)
• Backlit graduated scale and backlit indicators
• Built in electric torch for use in dark areas. (T110, T130, T150)
• Resistance testing to 1999 ohms. (T150)
• Audio on/off for testing in quiet areas. (T110, T130, T150)
• Improved probe docking for secure storage.
• Phase rotation indicator for 3-phase systems. (T110, T130, T150)
• Display hold freezes reading on display until your can view it comfortably. (T130, T150)
• Single-pole phase test offers fast identification of live conductors.
• Push-on probe tips, probe tip protector and storage accessory.
• Tip protector serves as an extra hand when opening UK electrical safety outlets.
• Low battery indicator.
