Proving Units

Wherever electrical safety depends on the ability of a test instrument to indicate if a circuit is live or isolated‚ best practice demands that the test device is checked before and after use.

Seaward’s range of proving units meets this requirement by providing a safe and simple means of proving the voltage indicating ability of potential indicators‚ test lamps and multimeters.

Designed to suit a range of applications in the electrical contracting‚ power utilities and industrial engineering sectors‚ Seaward proving units are both self-powered and self-testing‚ avoiding the need for a known supply point or bulky test equipment.
