Choosing the right voltage tester

There are a number of essential pieces of kit for any electrician, but few would see the same amount of regular use as voltage testers. Checking the availability of current passing through a circuit is a fundamental step in any electrical work, so having a convenient, safe and easy-to-use tool always on hand is vital.

That said, each electrician has their own needs and preferences, and there is an array of different types of voltage testers that may meet each individual's requirements. Whether you need a couple of different devices for different tasks, or just one all-purpose tester, Testo has the bases covered.

The 745 non-contact voltage tester

The testo 745 is a solution designed for speed – providing fast checking of suspected fault sources. The non-contact design ensures reliable voltage indication thanks to a filter for high-frequency interference signals.

With voltage detection ranging from 12 to 1,000 V AC, the 745 provides both phase detection and voltage indication functionality. With visual and audio confirmation of voltage, IP 67 protection and a built-in flashlight – all in a device weighing just 63 grams – it's an impressively handy option.

The 750 range of voltage testers

For those jobs where a little more detail is required during voltage testing, Testo's 750 range is a more-than-capable alternative. The first element of these devices that will stand out for users is the patented LED display, which wraps itself around three sides of the device, ensuring optimal visibility of results from any angle. 

Designed to handle all of the most important functions for voltage testing, continuity testing and rotating magnetic field measurement, the 750-2 and 750-3 are also suitable for single pole voltage testing. At the upper levels of functionality, the testo 750-2 and 750-3 feature an RDC/RC trigger function and measuring point illumination. 

For the fully premium experience, the 750-3 adds the convenience of an extra LC display to show current readings, offering optimal accuracy for those who require it. Each of the 750 series devices allow voltage testing from 12 to 690 V, and carry an IP 64 protection rating. 

Whether your demands will be covered by the efficient 745 non-contact voltage tester or you need to step up to the deeper functionality of the 750, Testo has the tools to help you get the job done. Get in touch today for more information about equipment for voltage testing.
