In these devices, use of platinum-rhodium alloys results in low signal strength, so under less extreme conditions, type K chromel-alumel components or type E chromel-constantan components are used instead. A technique using a class of these devices is often run in tandem with TGA and has largely replaced DTA. A namesake "block" containing a sensor is central to the Calvet-type setup of these devices, which can be used in the (*) "differential scanning" variety of their namesake technique. In chemistry labs involving these things, students may use the equation q equals C times quantity T-sub-f minus T-sub-i and may construct rudimentary versions of them out of two coffee cups and a two-holed lid. For 10 points, name these devices used in a technique that measures the heat of chemical reactions.
