Voltage Testers

When dealing with electrical systems, engineers often have to take measurements from obscure and inaccessible places, sometimes even in the dark. It was with these issues in mind that testo designed a new, innovative, Voltage Tester, in an attempt to provide a solution for common problems associated with testing voltage safely.

The all-round LED display and unique fibre-optic technology of Testo's 750 Voltage Tester range mean the voltage indication can be seen clearly from any position.
