| Provides more accurate results. Comprises a smaller inner nickel plated copper calorimeter vessel 75x50mm [height x diameter), enclosed in an outer vessel 100x75mm [height x diameter) with felt lagging in between them for minimizing heat loss. A close fitting bakelite lid is provided with a resistance coil mounted at the underside so as to be positioned sufficiently inside inner vessel and a pair of 4mm terminals at the top for electrical connections. The lid has provision for thermometer and stirrer. The resistance coil has recommended working current of 0.5A with a maximum of 1 A to minimize the local boiling of liquid.
