Fluke PRV240 Proving Unit
Verify your test tool without unnecessary exposure to shock and arc flash. The PRV240 reduces the need for personal protective equipment (PPE) when a known voltage source is not available.
Unique, compact, convenient
The Fluke PRV240 Proving Unit is a portable, pocket-sized, battery-powered voltage source. It is unique in that it sources stable ac and dc voltages for both LoZ and HiZ instruments.
