Abstract
According to a precise critical temperature indicator and a control method thereof of the present invention, the precise critical temperature indicator comprises as one body: a blocking boundary layer which is positioned between a spreading material member including an operation button and spreading medium members including a spreadable area for a spreading material; and a temperature sensor which is controlled and operated as the spreading material passes through the blocking boundary layer and contacts the spreading medium member according to a user's pressing of the operation button. As a result, operation of the temperature sensor is easily controlled using the operation button.
