An essential part of any electrician's selection of tools, the Fluke T90 contains all of the functionality you need for accurate and reliable two-pole voltage and continuity testing.
Part of Fluke's range of 'T' voltage and continuity testers, the T90 is the entry-level product in the range and is the most cost effective model for those wanting a voltage tester that simply does what it is meant to do.
Ideal for use in any low voltage electrical outlet, the T90 can be used to measure voltage across a range of 12V to 690V and continuity from 0 to 400kΩ with audible indication.
The tester uses LED indicators to show the current measurement taken. Other models in the Fluke T series also come with integrated LCD screens that show a full measurement value or provide vibration feedback.
