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 1000V AC.
When AC voltage is detected, the Testo 745 gives indication by flashing red LEDs and sounding a buzzer. You can easily determine the live and neutral pins of an outlet without lengthy and risky removal of the outlet. The Testo 745 NCV has a built-in low-pass filter which greatly reduces high frequency interference that can cause false indications.
The tester incorporates an LED flashlight that is bright and focused to make testing simple in dark spaces.
Resolution: 50 to 1000V AC (sensitivity 1), 12 to 1000V AC (sensitivity 2)
