Detecting live wires with the testo 745

For professionals and HVAC engineers testing voltage in electrical cabinets or a junction box, a non-contact voltage (NCV) tester can provide crucial levels of safety. Offering significant protection to those who spend their work days around energised electrical systems, NCV testers can prevent injury through clear indication of live wires. 

As part of its new electrical range, Testo has released the testo 745 NCV tester – able to quickly detect the presence of voltage in AC systems, with two sensitivity levels offering audible and visual indication.

Able to safely measure up to 1000 V, the testo 745 notifies the HVAC professional whenever live current is detected by way of audible buzzing tones and flashing red LED indicators. 

Save time on daily processes with the testo 745 

In business, management of your time is almost as imperative as the need for safety. The testo 745 can differentiate between neutral and hot legs within an AC outlet – preventing the need for a lengthy and total removal of the outlet itself.

A built-in flashlight offers the same level of reliability in darkened and enclosed spaces, while the additional Low Pass Filter reduces the potential for high frequency readings that can lead to interference and, subsequently, false indications.

Specifications you can rely on

As with all Testo products, the 745 NCV tester boasts an impressive array of features; rated to CAT III 1000 V and CAT IV 600 V and weighing in at just 63 grams, the lightweight testo 745 can provide dependable results when testing for voltage in any AC system. The testo 745 range offers a trusted level of durability – dustproof and waterproof to IP 67.

For HVAC engineers and professionals, safety is paramount. We at Testo understand this need for reliable, safety-conscious products, creating our new range of electrical measurement tools – including the testo 745 for speedy initial voltage checking wherever suspected electrical faults are concerned.
