Elcometer 456
Dry Film Coating Thickness Gauge
Probe Options

The Elcometer 456 Probes are intelligent. This means:

• All Ferrous (F) Models will accept any Ferrous Probe

• All Non Ferrous (N) Models will accept any Non Ferrous Probe

• All Dual Ferrous & Non Ferrous (FNF) Models will accept

• Any Ferrous (F)

• Any Non Ferrous (N) and

• Any Dual Ferrous/Non Ferrous (FNF) Probes

The Elcometer 456 Probes allow totally versatile application of the Elcometer 456 Coating Thickness Gauges to different coating thickness measurement tasks. Various probe ranges, resolution, size and access capabilities can be freely interchanged as required on both ferrous (F) and non-ferrous (N) metal substrates.

Combining over 45 years of probe design and build experience, with the latest materials and technology, the new Elcometer probes are even more accurate, repeatable and reliable than ever before. Available in a number of designs and scale ranges to meet your specific application, all probes are supplied with an Elcometer test certificate and a set of calibration foils†

Straight

• Measures coatings on both flat and curved surfaces

Right Angle

• For taking readings where access is restricted

Mini

• Ideal for edges, narrow pipes and small surfaces areas

PINIP

• Plug-in probes convert a separate to an integral gauge

Telescopic

• Extending right angled probes for out of reach areas

Waterproof

• Sealed for use under water at depth, even in diving gloves

High Temp

• For use on hot coated materials up to 250°C

Anodiser

• Chemical resistant washable probes ideal for the anodising environment

Armoured

• Probes with metal reinforced heavy duty cables

Soft Coating

• Large surface area probes for soft materials (HVCA approved)

Measurement Options

Ferrous (F) operation using electromagnetic induction probes for all non-magnetic coatings on a ferrous (magnetic) substrate, e.g. paint, plastic, enamel, powder, rubber, ceramic, galvanising, zinc, sprayed metal (aluminium or zinc), etc. on steel, cast iron, ferritic and duplex stainless steel, substrates etc.

Non-Ferrous (N) operation using eddy current probes for non-conductive coatings on non-ferrous metal substrates, e.g. anodising, paint, powder, lacquer, plastic, etc. on aluminium, brass, zinc, stainless steel, copper, titanium substrates etc.

Dual (FNF) operation combines the Ferrous and Non-Ferrous operation in a single probe. The gauge has user selection for auto or manual substrate determination.
