In practice

Read thick fire-protective and heavy-duty coatings up to 10 mm on steel, with a Φ20.5 mm spot that still fits formed sections and curved members.

0–10000 μm

Measure intumescent and heavy-duty protective systems on steel up to 10 mm in a single reading.

Ferrous steel only — not for aluminium or other non-ferrous substrates.

Φ20.5 mm minimum area

A Φ20.5 mm contact area and 0.5 mm minimum substrate keep thick-coating checks practical on formed sections.

At curved parts the radius must be at least 10 mm convex or 50 mm concave.
