ISOTEST inspect
Porosity Testing of Coatings
Benefits at a glance
Microprocessor controlled test instrument
Fully adjustable test voltage
Patented automatic regulation function
Power reserve for demanding test situations
Excellent test sensitivity via menu
Easy to read, alphanumeric LCD
Easy operation of all functions
Safety mode – selectable from the menu
Acoustic and visual indication of porosity
ISOTEST inspect 4.0
Test voltage 0.5 – 4.0 kV, 0.5 kV steps
ISOTEST inspect 8.0
Test voltage 1.0 – 8.0 kV, 1.0 kV steps
These instruments have been specially developed for testing sensitive coatings like
FBE, enamel, epoxy, Halar etc.
Benefits: An intelligent signal analysis makes it possible to test completely coated parts.
The menu-driven sensitivity of the instrument guarantees exact test results. The integrated
pore counter makes it easier to meet works specifications and standards.
ISOTEST inspect 35
Test voltage 5 -35 kV, 0.1 kV steps
Performance for every application
Benefits: Energy reserves for the most demanding test situations, thanks to impulse voltage
technology. The ISOTEST inspect can cope with large diameter, humid, dirty and even
slightly conductive surfaces. The battery strength display, hours run meter, safety button
activation via the menu, the easy to use membrane keyboard and display bear witness
to the wide range of possible uses.
