Digital Insulation Tester with 3 Test Ranges and unique Auto Null function



The K3005 has three test voltage ranges: 250V, 500V and 1000V and is equipped with a unique bargraph display that illustrates to the user that the insulation under test meets the minimum voltage required by the regulations.

An advanced feature included in both models is Auto Null mode, this unique function subtracts the test lead resistance during continuity tests, ensuring repeatable accuracy.

The top of the range K3005 is equipped with Trac-Lok circuits that improve battery life considerably, thus saving the user money.

Another great feature is the EL Backlight on the display which enables readings to be taken in dimly lit areas.
