This probe is ideal for measuring electrically non-conductive and non-ferrous metal coatings on steel or iron base materials (ISO/FE and NF/FE). It is well suited for measurements of electroplated metal coating thicknesses such as zinc and chrome.
This probe is ideal for measuring electrically non-conductive coatings on non-ferrous metal base materials (ISO/NF). It is highly accurate when measuring thin coatings (e.g. thicknesses between 2 to 5 µm). Common applications include paint, varnish or plastic coatings on aluminum, copper or brass.
This probe is ideal for measuring coating thicknesses on virtually all metal substrates. Also, it is well suited for measurements on rough surfaces due to the large probe tip.
This probe measures the electrical conductivity of non-ferrous metals according to the Eddy current method. It is perfect for material sorting, monitoring of heat treatment and analysis of structure conditions. This probe is often used for measuring the electrical conductivity of plated aluminum components in the aerospace industry.
This probe is ideal for measuring electrically non-conducting coatings on non-ferromagnetic metal substrate materials (ISO/NF). It is well suited for measurements in pipes, bore holes, grooves, etc. The smallest permissible inside diameter is 9 mm while the maximum insertion depth is 150 mm.
This probe is ideal for duplex measurements on sheet metal with electrolytically or slight hot-dipped galvanized coatings. The individual coating thicknesses of the duplex coating system are measured simultaneously and displayed in the instrument separately. Hot-dipped galvanized zinc coatings without pronounced zinc-iron diffusion zone can also be measured. This probe can also be used as a dual probe with automatically base material recognition under the coating. It is commonly used in the automotive industry.
This probe is ideal for measuring copper coating thickness even under thin Sn- or SnPb coating e.g. in metal through-holes in printed circuit boards with a range of 0.8 to 2 mm diameter.
This probe is perfect for measuring non-conductive and non-ferrous metal coatings on steel or iron base materials (ISO/FE or NF/FE). It is especially suited for thick coatings and has high measurement precision on rough surfaces.
This angled probe measures electrically non-conductive coatings on non-ferromagnetic metal substrate materials (ISO/NF). It is especially suited for measuring paint coatings on hot-dipped galvanized steel components with a zinc thickness of > 80 μm.
This probe is ideal for measuring electrically non-conductive and non-ferrous metal coatings on steel or iron base materials (ISO/FE and NF/FE). It is well suited for the measurement of thin coatings and features unparalled precision when measuring rough surfaces.
