Thin Film Porosity Testing.
These units are also known as wet sponge testers, low voltage
holiday detectors, low voltage porosity detectors or pin
hole detectors.
Conforms to: ASTM G62-A, NACE RP0274-98,
ASTM G-6, AS3894.2 & AS1580.485.1
Features
- LED display of voltage
- Internally mounted 9 Volt battery
- Low battery condition LED indicator
- Telescopic handle for user confort (extends
