Circograph CI

Contactless eddy current testing of bright material

Compact test system for longitudinal surface defects

The CIRCOGRAPH CI combines a compact design with intuitive operation in one high-precision rotating test system. The CIRCOGRAPH CI features a user-friendly operation unit as well as easy “Turn-and-Push” rotary switch. The 2-channel system can be adjusted optimally to suit your test tasks thanks to a large range of different rotating heads. Longitudinal defects in the material surface can thus be detected from depths as low as 30 µm.
