The testo 745 non-contact voltage (NCV) tester quickly checks for the presence of voltage in AC powered systems. It can be safely used up to 1000 V AC. When AC voltage is detected, the testo 745 gives an indication, by flashing its red LED tip, and buzzing its internal audible buzzer. You can easily determine the hot and neutral legs of an outlet, without the time consuming and risky removal of the outlet from the outlet box.

Two sensitivity levels, with audible and visual indication
Flashing LED indicates sensitivity range, down to 12 V AC, or standard range above 50 V AC
Differentiates hot from neutral in AC outlets
Low pass filter reduces false indications

The testo 745 NCV has a built-in low pass filter that greatly reduces high frequency interference, which causes false indications. The built-in LED flashlight is bright and focused, to make testing simple in dark spaces. It also includes a low battery indication, and is IP67 rated waterproof and dustproof. The testo 745 is rated to CAT III 1000 V and CAT IV 600 V.

Testo’s history of efficiency, innovation, and quality now extends into the entire electrical lineup. Once again, Testo brings high value, feature-packed products to the HVAC contractor market.
