PCWI Compact DC High Voltage Holiday Detector


Detection of holidays - pinholes, bubbles, or porosity - in coatings is crucial to preventing failure of protective coating. PCWI HIGH-VOLTAGE HOLIDAY DETECTORSwith ABS body housing, are small and light-weight - only 2.2 kg - fully-portable holiday detectors suitable for the detection of flaws in di-electric coatings on conductive substrates, including concrete. Available as DC15 or DC30 models, PCWI Holiday Detectors have fully-adjustable voltage control in 100 v increments over the full range of the detector, providing accurate, precise voltage output for all coating thicknesses where high-voltage testing is required. Constant current source maintains applied test voltage; full test current at low voltages permits testing of low coating thicknesses.

A variety of electrodes are available to enable use in virtually any coating testing situation, including:

flat brass or silicone brushes up to 24" long and fan brushes

 

 

 

 

internal brass-bristle pipeline electrodes (spiral to 3", disc to 20" internal diameter)

 

 

internal brass cone electrodes to 4"

 

 

pipeline coils up to 56" outside diameter

 

 

 

 

brass rolling outside rings and half-rings for outside diameters up to 24" OD

 

 

 

 

PCWI High Voltage Holiday Detectors are ideal for pipeline coating applications, storage tanks including municipal water tanks, valves, bridges, and other structural coatings projects. The clip-on battery pack allows use in the field as well as in the lab or paint shop environment; battery can be operated off AC electrical supply via the charger during recharging, and is fully recharged in 10 hours. Complies with NACE standards SP0490, SPO274, and SP0188.
