Iron-based probes measure the thickness of non-magnetic coatings on ferromagnetic substrates. The Elcometer 456 is an iron-based instrument that recognises any iron-based probe. Non-ferrous probes measure the thickness of non-conductive coatings on non-ferrous metal substrates and the Elcometer 456 is approved for any non-ferrous probe. The dual-purpose FNF probe can be used for both ferrous and non-ferrous applications, and has the function of automatic substrate identification. The Elcometer 456 FNF Class Instrument recognises all iron-based, non-ferrous and dual-purpose FNF probes.
Elcometer probes are available in a maximum operating temperature of 80°C (176°F), in addition to the 150°C (300°F) for split iron-based probes and 250°C (480°F) for high-temperature PINIP. The specified temperature is at the substrate temperature and the duty cycle of the probe needs to be reduced to ensure a minimum of temperature accumulation within the probe.
All Elcometer probes come with a certificate of test and a set of calibration diaphragms for the probe's scale range.
To meet the specific application requirements of our customers, all Elcometer 456 probes are fully interchangeable.A wide range of designs and graduations are available.
| Probe image | Probe name and application |
![]() | Straight probe Coatings can be measured on both flat and curved surfaces |
![]() | Miniature probes It is the perfect product for measuring edge coatings, narrow tube coatings or coatings on small surface areas |
![]() | Right-angle probe It is used to measure hard-to-reach places |
![]() | PINIP™ probes Plug-in probes to transform a split instrument into a monolithic instrument |
![]() | Distal probes Extend the right-angle probe to reach places that are difficult to reach with conventional probes |
![]() | Scanning probes These probes are fitted with interchangeable probe caps – allowing the user to take a single reading or scan large surface areas without damaging the probe |
![]() | Waterproof probe Closed design, used in deep water, even wearing diving gloves does not affect use |
![]() | High temperature probes Can be used on coatings up to 250°C (480°F). |
![]() | Anodizing probes Resistant to chemical solvents, it is ideal for use in anodizing environments |
![]() | Armoured probes The probe comes with a heavy-duty metal-reinforced cable that reduces the risk of cable damage |
![]() | Soft-coated probes Large-area surface probe for inspection of soft overlay materials (HVCA certified) |
![]() | Professional probes These probes can be used to measure on specialized substrates such as graphite or plated components |
