The frigorimeter is a device for measuring the average amount of cooling . It was developed by the naturalists Carl Dorno and Rudolf Thilenius .

The device is used to determine the amount of heat required to keep a cooling test body (black box or solid copper sphere 7.5 cm in diameter) constant at a temperature of 36.5 ° C (human skin temperature). The electrical heat supply necessary to maintain this temperature corresponds to the amount of heat that is withdrawn from the test body by cooling. The electrical power with a known size of the surface of the test body corresponds to the desired measure for the mean cooling amount.
