Expendable sampling cups used to measure the temperatures at which thermal arrests occur in the cooling curve of solidifying molten iron.

The shell is manufactured using moulding sand and has an internal type K thermocouple protected by a Quartz™ tube, designed for fast response and accurate measurement. The base of the cup has a moulded coupling for connection to a sampling cup stand; this then feeds back to the Digicarb/14 or alternative instrumentation for analysis.

MAISC cups can be used to determine carbon equivalent liquidus (%CEL) in hypoeutectic iron and for analysis of the cooling temperature and arrest points.

MATSC cups are supplied with tellurium cement which mixes with the liquid iron and solidifies white; this allows for the additional analysis of carbon (%C) and silicone (%Si) percentage in hypo and hypereutectic iron.
