Socket & See SP200 Professional Proving Unit

Check that your two-pole voltage tester is working correctly with this professional proving unit.

Also suitable for use with test lamps and multimeters, the SP200 generates an AC waveform to simulate a true voltage test with step voltage LEDs as each voltage threshold is generated. It can display that 50, 100, 230, 400 and 690V.

Compact and lightweight, this unit is ideal for taking with you as part of your toolkit and should be used both before and after testing to verify the correct continued operation of your tester(s).
