These robust and user-friendly instruments are used for assessing the cupping ability of coatings applied to metal sheets up to 1.2mm (0.05") thick.

The Elcometer 1620 has a 27mm (1.06") diameter hardened steel die in a clamping device and a 20mm (0.79") diameter punch. A hand-rotated crank and reduction drive moves the punch progressively into the sample. This method gives good repeatability.

A motorised version is also available which replaces the manual crank handle. This ensures perfect reproducibility with constant cupping speed of 200µm per second (7.9mils per second).

The Elcometer 1620 is available with either an analogue or a digital gauge and both models are supplied with an illuminated magnifier to accurately view the deformation's results. A CCD video system can also be supplied as an accessory.

The Elcometer 1620 provides accurate (10µm/0.4mil) readings of the cupping depth on an integrated gauge and direct viewing of the fissures cracks and tears in the coating.
