The Fluke T110 Voltage and Continuity Tester with flashlight, backlit LED display, and clear audible and vibration signals will help you work with confidence and get the test results you need. Voltage and continuity testers measure voltage, but it's just as important to tell you there is NO voltage before you start working on a circuit. To be confident in your voltage and continuity tester, you need the most robust product of its kind. That's exactly what Fluke's advanced voltage and continuity testers give you. Fluke knows that failures often come from the test lead. The test lead is the most stressed part of a voltage and continuity tester - it's constantly bent, twisted, and stressed. If the test lead breaks, there's an increased safety risk. Industry standards require that test leads be tested to a 45-degree bend and still work after 5,000 bend cycles. Fluke subjects the test leads of the new voltage and continuity testers to significantly higher stresses. The test lead is bent by more than 150 degrees in each direction. For this reason, we offer you the longest warranty that Fluke has ever offered for this type of device.
