Iron-based probes measure the thickness of non-magnetic coatings on ferromagnetic substrates. The Elcometer 456 Iron-based instrument accepts any iron-based probe. Non-ferrous based probes measure the thickness of non-conductive coatings on non-ferrous metal substrates. The Elcometer 456 non-ferrous based instrument accepts any non-ferrous based probe. The dual-purpose FNF probe can be used for both ferrous and non-ferrous applications and has the function of automatically identifying the matrix. The Elcometer 456 FNF category instrument accepts all ferrous, non-ferrous and dual purpose FNF probes.
Elcometer probes are available with a maximum operating temperature of 80°C (176°F) except for the split iron-based probe which is 150°C (300°F) and the high-temperature PINIP which is 250°C (480°F). The specified temperature is the substrate temperature and the probe duty cycle needs to be reduced to ensure a minimum temperature build-up within the probe.
All Elcometer probes come with a certificate of inspection and a set of calibration diaphragms suitable for the probe's scale range.
To meet customers' specific application requirements, all Elcometer 456 probes are fully interchangeable and available in a wide range of designs and calibration ranges.
