PURPOSE:To facilitate the sampling of a fixed amount of water with a fixed temperature in a short time, by draining water from an outer tank which holds water of a fixed temperature to a fixed level until it reaches the prescribed level after supplied excessively into an inner tank. CONSTITUTION:While solenoid valves 14 and 15 communicating with a hot water tank 16 are opened and closed measuring the temperature of water in an outer tank 11 with a sensor 28, water is agitated with the rotation of a motor 24 to adjust the temperature thereof to a specified level. Then, a pump 38 is driven to supply water in the outer tank 11 excessively into an inner tank 30 and then, a pipe 44 is moved vertically with a lift mechanism 55 according to the necessary amount of water. Then, with solenoid valves 47 and 49 opened, a pump 51 is driven to drain excessive water outside and water of a fixed temperature is sampled by a prescribed amount. Thereafter, the rise in the temperature of water in the inner tank 30 is measured with a temperature sensor 28 stirring water in the inner tank 30 with an agitator 36 thereby enabling the measurement of heat generated from a sample to be measured.
