Lightweight, compact SPY Model 670 holiday detectors set up easily — simply connecting to conductive metal under the coating. This design affords less connections, fewer potential problems, and easy troubleshooting, says the maker.
SPY can incorporate a wetted flat or roller sponge as an electrode to detect holidays with pinhole accuracy. The 3-lb unit also reduces operator fatigue.
A roller sponge electrode option also reduces inspection time for large flat surface areas. The flat sponge best suits contoured surfaces and tight space inspections.
Coating defects as thin as 1-mil are detected with accuracy — and without harm to coating. An electrical path is completed when a holiday is found, activating a signal light and horn.
Complete SPY holiday detectors data are free.
