摘要： Provided is an optical reaction measurement device that measures whether a reaction is occurring between a sample and a reagent, or how a reaction is progressing, on the basis of changes over time of optical properties of a liquid mixture of the sample and the reagent. The preparation time required for tasks such as mixing the sample and the reagent is predetermined, and when a start switch on the measurement device is turned to “on,” a timer starts running, and the time remaining until the preparation time begins is shown to an operator as a countdown. When the count reaches zero, the operator is informed that the preparation time has begun. The amount of time that has passed since the preparation time began is used as time data to accompany measurement data, and optical property data from after the end of the preparation time is used in analysis.
