PROBLEM TO BE SOLVED: To effectively prevent a reduction in measurement accuracy due to change in an inspection cartridge and an environment temperature.SOLUTION: An automatic analysis device comprises: cartridge conveyance means 2 for carrying in and out an inspection cartridge 10; sample-reagent dispensing means 3 for dispensing a sample and a reagent from the inspection cartridge 10 within an inspection stage KT into a reaction cell 11c; measurement means 4 for measuring a reaction between the sample and the reagent in the reaction cell 11c; a thermostat bath 6, heated by a heating source 6a, for keeping a liquid temperature in at least in the reaction cell 11c of the inspection cartridge 10 within the inspection stage KT at a predetermined constant environment temperature; and thermostat bath control means 7, having a temperature detector 7a capable of detecting an internal environment temperature of the inspection stage KT, for controlling a set temperature of the heating source 6a, on the basis of the internal environment temperature detected by the temperature detector 7a, so that when the internal environment temperature is lower than a predetermined threshold, the set temperature of the heating source 6a of the thermostat bath 6 is raised as compared with a case where the temperature is greater than or equal to the threshold.SELECTED DRAWING: Figure 1 |
