The Elcometer 355 Probe Range is the set of interchangeable probe modules for the Elcometer 355 Coating Thickness Gauge, covering both ferrous (F) and non-ferrous (N) metal substrates across a wide span of coating thickness applications. Because the modules can be freely swapped, a single gauge handles different substrates, geometries and thickness ranges without the need for a separate instrument for each job.

Accurate dry film thickness is the difference between a coating that protects and one that fails: too thin and corrosion protection is compromised, too thick and adhesion and cost suffer. Most probes in the Elcometer 355 Probe Range achieve an accuracy of ±1% of the reading on a variety of coatings and surfaces. Scale 1 probes (F1, N1) measure 0 to 1500μm with resolution down to 0.1μm at the low end, Scale 2 probes (F2, N2) extend to 0 to 5mm for thicker films, and Scale 4 probes (F4) cover 0 to 250μm at 0.1μm resolution.

Probe styles of the Elcometer 355 Probe Range suit different access. Standard probes need around 85mm headroom, telescopic versions extend from 410mm to 1100mm and drop the minimum headroom to 30mm (F1 Telescopic), and the F4 Right Angle (long) reaches into tight spots with just 18mm headroom on samples down to 3mm diameter. Used in coatings inspection and corrosion control, the Elcometer 355 Probe Range is supplied by BAMR, South Africa's authorised distributor.
