PCWI Compact DC Porosity (Holiday Detector)
Model : DC-15, DC-30
Complies with the requirements of AS3894.1-2002 and Nace Standards: SP0490-2007.
Applications
· Used for detection of coating porosity (pin-holes, or holidays) in dielectric (insulation type) coatings on conductive substrates, including concrete.
· Suitable for Production Pipeline Coating operations, Tank-work and Structures. Ideal for use
on storage tanks, valves and pipelines.
· Housed in a fuly portable ABS case, the Detectors deliver stabilised DC output of up to 30kv. Constant current source maintains applied test voltage. Full test current at low voltages (where it is needed most) when testing at low film builds (eg: 150µm.as per AS3894.1-2002).
Incorporating momentary-on and continuous-on switches (mounted on the front panel), alowing the units to be switched on momentarily for safety, or run continuously.
No need to swap power supplies or change probes to change voltage . the Detectors have clip-on battery packs that can be separately charged. Can operate of mains power (via the charger) during recharging. Fuly recharged in 10 hours. Regulated DC output fuly adjustable. Applied voltage and battery condition are co
Controls
1 LCD display (including battery condition indicator)
2 Voltage control (10 turn)
3 Visual alarm indicates when fault is found
4 On switch
5 Off/test switch
6 Sensitivity control for the alarm
7 Audible alarm when fault is found
8 High Voltage probe connector
9 Fuse (1.6A slow blow) 5 x 20mm
10 Earth connection point
11 Charge connector . alows operation while charging is in progress
12 Clip-on battery pack
13 Earphone (connected on opposite side)
