PURPOSE: A device for controlling the amount of vapor and a method using the same for calculating a reaction reference of a fluorescent substance are provided to measure a change in a fluorescent spectrum of the fluorescent substance sensitive to moisture under different conditions of vapor amounts, thereby calculating the fluorescent change reference caused by a minute change in the amount of the vapor. CONSTITUTION: A device for controlling the amount of vapor comprises a vaporizing chamber(110), a moisture supply unit(120), and a reducing chamber(130). The vaporizing chamber includes a pressure controlling device(111), a temperature controlling device(112), a pressure gauge(113), and a thermometer(114). The moisture supply unit supplies a fixed amount of moisture to the inside of the vaporizing chamber. The reducing chamber is joined to one side of the vaporizing chamber, thereby being connected to the vaporizing chamber by opening a valve. A volume of the reducing chamber is smaller than that of the vaporizing chamber. [Reference numerals] (AA) Measurement of a change in light
