About this product

The Elcometer 456 Dry Film Thickness Gauge Probe Options are the interchangeable measurement probes for the Elcometer 456 coating thickness gauge, available in a range of designs and scale ranges to suit different substrates and access requirements. Choosing the correct probe matters because coating thickness directly governs corrosion protection and finish quality, and the wrong probe geometry or scale range either cannot reach the test point or cannot resolve the coating accurately.

Ferrous (F) probes measure non-magnetic coatings on ferro-magnetic steel substrates, non-ferrous (N) probes measure non-conductive coatings on non-ferrous metals, and dual ferrous non-ferrous (FNF) probes handle both with automatic substrate detection. All probes are fully interchangeable across the relevant gauge. Scale ranges run from 0 to 500um up to ferrous 0 to 25mm and non-ferrous 0 to 30mm, with resolution as fine as 0.1um on the lower ranges and accuracy of 1 to 3% or a fixed tolerance figure depending on scale.

Probe styles include standard straight, mini, right angle, plug-in, telescopic, scan, waterproof, high temperature for hot coated materials up to 250C, anodising, armoured cable, soft coating and specialist probes for substrates such as graphite or electroplated components. Every Elcometer 456 Dry Film Thickness Gauge Probe Option is supplied with a test certificate and a matching set of calibration foils. Used in coatings inspection, corrosion protection and industrial finishing, the Elcometer 456 probes are supplied by BAMR, South Africa's authorised Elcometer distributor.

Decision guide

When to use the Elcometer 456 Probe Options

Choose a 456 probe when the standard straight probe cannot reach or suit the part being measured. All 456 probes are fully interchangeable, so you can match the gauge to awkward access, hot coatings, underwater work or specialist substrates without changing the instrument.

1
Reaches awkward geometry
Mini, right angle and telescopic probes take readings on edges, restricted areas and out-of-reach surfaces where a straight probe will not fit.
2
Built for tough conditions
Waterproof probes are sealed for use underwater at depth and high temperature probes read on hot coated materials up to 250C, extending the gauge to jobs a standard probe cannot do.
3
Matched to the coating range
Probes come in several scale ranges, so the gauge can be set up for thin coatings or for thick films as the application demands.
4
Faster large-area scanning
Scan probes with replaceable caps let you take individual readings or sweep large surfaces without damaging the probe, speeding up area inspection.

Consider instead

Lower-budget alternatives

Answers

Frequently asked questions

Are all Elcometer 456 probes interchangeable between gauge bodies?

Yes. All Elcometer 456 probes are fully interchangeable and are available in a number of designs and scale ranges to suit specific applications.

What scale options are available, and how do their ranges differ?

Scale 0.5 covers 0 to 500 micrometres, Scale 1 covers 0 to 1,500 micrometres, Scale 2 covers 0 to 5mm, Scale 3 covers 0 to 13mm, and Scale 6 covers ferrous 0 to 25mm or non-ferrous 0 to 30mm. Scale 7 covers 0 to 31mm. All carry calibration certificates.

Are there probe options for access-restricted or deep-recessed areas?

Yes. Right-angle probes, 45-degree probes, and 90-degree mini probes are available in lengths from 45mm to 400mm. A telescopic probe extends from 56 to 122cm.

Which probe is suitable for underwater or wet environment use?

Waterproof ferrous probes (T456CF2SW series) are available with cable lengths of 1, 5, 15, 30, 50, and 75 metres. Sealed mini probes are also available for wet conditions.

Is there a probe option for high-temperature surfaces?

Yes. The Hi-Temperature PINIP probe (T456CF2PHT) is rated for use up to 250 degrees C, on the Scale 2 range of 0 to 5mm.
