Modiewark non-contact voltage detectors significantly reduce the risk of electrocution. Other scenarios include battery powered vehicles, trains, trams, planes, underground mining and power generation and storage.

Q. What is the range of voltage detected?

There is a Modiewark available for detecting AC/DC voltage from below 50 to over 1,000,000 volts.

Q. How can I be sure Modiewark works?

Modiewark invented the non-touch voltage tester over 40 years ago and is used to ensure the safety of personnel by large organisations around the world. We are continually improving and expanding our range of electronic voltage detectors.
