Measure voltage … without test leads
We know working in electrical boxes jammed with wires can be challenging when you’re trying to find a safe metallic contact point. Now, with Fluke’s T6-600 or T6-1000 with integrated FieldSense technology, you can quickly and easily take measurements by sliding the open fork over a conductor to see the voltage level without the need for test leads.*

Why use the T6 Electrical Tester?
Electricians often work in boxes jammed with wires, where finding a safe metallic contact point can be a challenge. With the T6-600 or T6-1000 you take measurements by sliding a single wire into the open fork.
How FieldSense Works
FieldSense technology is truly a breakthrough in how voltage is measured. While other open fork testers detect a magnetic field to show ac current, FieldSense technology detects an electrical field. This field interacts with a reference signal created by the T6 tester, creating a voltage value on the tester’s display.
Who needs a T6 tester?
Commercial and light industrial electricians can use T6 Electrical Testers for most everyday measurements. These devices easily fit in your pocket, making them easy to access on the front-line for electricians of all industries.
* Voltage measurement requires capacitive path to ground, provided through user in most applications. Ground connection via test lead may be required in some situations.Measure voltage up to 1000 V ac through the open fork, without test lead contact to live voltage.+ Without opening covers or removing wire nuts. On wires up to AWG 4/0 (120 mm2), carrying as much as 200 A. It will change your job. Safer. Faster. Easier.
