Overview
The testo 755 current/voltage testers are fast and easy to use, especially when you are testing many circuits. The convenient open-jaw current tester automatically turns on when voltage exceeds 6V. It then auto-selects the correct parameters and range for your test. These rugged testers are suitable for virtually all your daily electrical measuring tasks.
The instruments include important functions such as current, voltage, resistance & continuity. The integrated flashlight enables users to work in poorly lit areas. The overall design is for convenient testing including interchangable measuring tips which can be easily updated and maintained. A convenient lead holder is integrated into the housing for safe and easy storage.
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. Compared to the testo 755-1, the testo 755-2 has an increased voltage range of up to 1,000 V and enables rotating magnetic field measurement along with single pole voltage testing to determine quickly whether conductors are live.
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 VAC. When AC voltage is detected, the testo 745 gives indication by flashing RED LEDs and buzzing audible tones. You can easily determine the hot and neutral legs 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 which causes false indications. The included LED flashlight is bright and focused to make testing simple in dark spaces. It also includes a low battery indication and is waterproof and dustproof rated per IP 67. The testo 745 is rated to CAT III 1000V and CAT IV 600 V.
