Joule's Calorimeter, useful for conducting the electrical method of determining the specific heat capacity of a liquid. Comprises of a nickel plated copper calorimeter measuring 3" tall and 2" in diameter. Lagged and enclosed within an outer vessel measuring 4" tall and 2.75" in diameter. A close-fitting ebonite lid is provided with a wire stirrer, and a pair of 4mm socket terminals connected to a constantan wire heating coil. The resistance of the coil is approximately 6 ohms and should be used with a current of 0.5 A with a maximum of 1 A (power supply not included). Designed for use in professional laboratories, but is an ideal choice for science classrooms and household use. *Thermometer is not included.
