PROBLEM TO BE SOLVED: To accurately determine the quality of vapor by sampling the vapor as condensed water in fixed stable conditions and measuring the water quality of the condensed water. SOLUTION: This vapor quality monitoring device for cooling/liquefying vapor heat-exchanged with refrigerant distributing with a partition wall therebetween comprises a flowmeter and a temperature gauge provided in a condensed water outlet out of which the vapor cooled/liquefied into condensed water flows. It computes a measured value signal from the flowmeter, as a base, and controls the opening of an automatic valve provided in the condensed water outlet to control the flow amount of the condensed water to be a predetermined value. Then, it computes a measured value signal from the temperature gauge, as a base, and controls the opening of the automatic valve provided in a refrigerant inlet or outlet to control the heat exchange rate of the vapor to the refrigerant and control the temperature of the condensed water to be a predetermined value.
