Parr’s 6772 Calorimetric Thermometers sport 0.0001°C temperature resolution rates over ranges of 0 to 70°C, and sets of operating controls. The apparatus showcases heat leak and thermochemical calculations that are both required for making Parr 1341 Calorimeters, 6755 Solution Calorimeters, and 6725 Semimicro Calorimeters automated. It also features a set of digital communication configurations, such as the Ethernet and serial ports.
