Article No. 11096

QNix 4200 Int Probe Fe, 120 mil

The QNix®4200 (for measurements on Fe) and the QNix® 4500 (for measurements on Fe and NFe) are coating thickness gauges with reliable results and easy to use. They are available in a variety of different versions, such as with an integrated or cable probe or with an extended measuring surface of up to 5 mm. This lets you cover a very broad range of applications if need be.

    * of the measurement
    Fe* Measuring of non-ferroumagnetic coatings on ferromagnetic substrate, for example measuring on steel- or iron-substrates.
    NFe* Measuring on non-ferromagnetic and electrically non-conductive coatings (insulating coatings) on non ferromagnetic and electrically conductive substrate, for example measuring on aluminum-, zinc-, brass-, and certain stainless (high grade) steel substrates.
