Q. Do non-touch DC testers even work?

The Fire Rescue DC50 and the multi-setting DC80 are the only true non-contact testers of Direct Current on the market today. Only rely on Modiewark.

Q. What about solar electricity?

Wherever batteries are involved, DC electricity is a threat. When a house with solar panels is on fire, both AC and DC testing is essential. 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.
