Reliable voltage measurement with the testo 750

As any contactor will know, sometimes you are required to take measurements from less than ideal positions. This is certainly true when attempting to take electrical systems, as engineers will often have to do so from an obscure and inaccessible places, sometimes even in the dark.

It was these issues in mind that testo designed this new Voltage tester, in an attempt to provide a solution for common problems associated with taking measurements safely.

With the launch of a brand new and innovative ranch of electrical measuring instruments, testo have tackled a number of ongoing problems engineers encounter on a daily basis.


360-degree display for optimum visibility

One of the key advantages of the testo 750 Voltage Tester range is the visibility of results. Thanks to its unique 360 LED display, you can see the results of the measurement from any angle. This has proved incredibly useful when accessing those tough to reach areas, as the reading is clearly visible from all angles.

As mentioned above, based on customer research the 750 was designed specifically to overcome issues that engineers cope with every day. The probe and instrument itself is robust so will likely outlast any lower quality alternative, whilst the ‘easy-grip’ and ‘anti-slip rings’ mean they won’t be in danger of slipping out of your hands.


Well-Illuminated for extra safety

The testo 750 range fulfils standard DIN-EN 61243-3:2010. In order to fully meet this requirement, it has been fitted with a triangular LED.

All versions meet both CAT III 1000 V and CAT IV 600 V. They also have low input impedance and continuity testing, phase sequencing, water/dust protection in accordance to IP 64. What’s more, they have an additional feature meaning they can even detect voltage when batteries are completely empty.

As an additional benefit, the Voltage Tester has been equipped with a built-in flashlight for those situation when the light level is low and it’s tough to see what you’re doing.
