Callendar & Barne's Apparatus ( Continuous Flow) Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-11966
Quick Answer: The Callendar & Barne’s Apparatus (Continuous Flow) is a continuous flow calorimeter for finding the specific heat capacity of a liquid and the electrical equivalent of heat. Liquid from a constant-level tank flows through a 360–400 mm horizontal borosilicate tube past a spiral heating coil.

About This Product
Once the flow and heating are steady, the inlet and outlet temperatures stop changing, so heat lost to the surroundings is the same in every run and can be removed by repeating with a different flow rate and current. This avoids the cooling correction needed with a simple calorimeter and gives the specific heat capacity of the liquid or the electrical equivalent of heat. The Callendar & Barne's Apparatus ( Continuous Flow) can be supplied on export terms to Guinea-Bissau, Venezuela, Gabon, Georgia, Bangladesh and Lithuania.
