Art.-No. 0113510001

ISOTEST® inspect 8.0
Test voltage 0.5 - 8.0 kV, adjustable in steps of 0.5 kV
The holiday detectors version ISOTEST® inspect 8.0 have been specially developed for testing sensitive coatings like FBE, enamel, epoxy, Halar etc. An intelligent signal analysis makes it possible to test completely coated parts. The menu-driven sensitivity of the instrument guarantees exact test results.

ISOTEST® inspect 35
Test voltage 5 - 35 kV, adjustable in steps of 0.1 kV
Performance for every application. Energy reserves for the most demanding test situations, thanks to impulse voltage technology. The ISOTEST® inspect 35 can cope with large diameter, humid, dirty and even only slightly conductive surfaces.
